48 mistakes · 6 categories
"I am agree"
WRONG. "Agree" is a verb, not an adjective. Use "I agree" — never combine "am" with "agree".
Correct: "I agree with your point about the deadline."
"he don't know"
WRONG. Third-person singular (he/she/it) always takes "doesn't", not "don't", in the simple present.
Correct: "He doesn't know the answer yet."
"since three years"
WRONG. Use "for" with a duration of time. "Since" is used with a point in time, not a length of time.
Correct: "I have been studying English for three years."
"more better"
WRONG. "Better" is already the comparative form of "good". Adding "more" creates a double comparative.
Correct: "Your second draft is much better than the first."
"I have 25 years"
WRONG in English. Unlike Spanish or French, English uses "to be" for age, not "to have".
Correct: "I am 25 years old."
"we must to go"
WRONG. Modal verbs like "must", "can", "will", and "should" are always followed by the bare infinitive (no "to").
Correct: "We must go now or we will miss the train."
"informations"
WRONG. "Information" is an uncountable noun and has no plural form. Use "pieces of information" if you need to count.
Correct: "She gave me some very useful information about the visa process."
"I am boring"
WRONG (usually). "Boring" describes the thing causing boredom. Use "bored" to describe how you feel.
Correct: "I am bored in this meeting" vs "This meeting is boring."
"affect vs effect"
"Affect" is almost always a verb ("to affect"). "Effect" is almost always a noun ("an effect"). "The rain affected the game" / "The rain had a big effect on the game."
"Stress can affect your health. The effects of stress on the body are well-documented."
"lend vs borrow"
"Lend" means to give something temporarily (you are the owner). "Borrow" means to take something temporarily (you are the recipient).
Correct: "Can you lend me your pen?" / "Can I borrow your pen?"
"make vs do"
"Make" is used for creating or producing things. "Do" is used for activities and tasks. These collocations must be memorised.
"Make a decision, make a mistake, make an effort" vs "do homework, do the washing, do your best."
"say vs tell"
"Tell" is always followed by a person (tell someone). "Say" is not — it focuses on the words spoken.
Correct: "She told me the news" / "She said the news was shocking."
"watch vs look vs see"
"See" is passive (happens without effort). "Look" means to direct your eyes. "Watch" means to observe something moving or changing over time.
"I saw a bird" (accidental) / "Look at that bird!" (directed) / "I watched the bird for ten minutes" (sustained).
"fun vs funny"
"Fun" means enjoyable. "Funny" means amusing or humorous — it causes laughter. Calling someone "very fun" is acceptable in informal AmE, but "funny" has a different core meaning.
"The party was fun" (enjoyable) vs "The comedian was funny" (made people laugh).
"sensitive vs sensible"
"Sensible" means having good judgement (a false friend for French/Spanish speakers). "Sensitive" means quick to respond emotionally or physically.
"Wear sensible shoes for the hike." / "She is very sensitive to criticism."
"actually vs currently"
"Actually" does not mean "at this moment" — it means "in fact" or "to be honest". "Currently" means "at this time". Many learners swap these.
Correct: "I actually prefer tea to coffee" / "She is currently working in Berlin."
"in the next week"
WRONG. Do not use "the" with "next" or "last" when referring to the week/month/year relative to now. "The" makes it sound distant and odd.
Correct: "I will call you next week." / "She left last Monday."
"married with"
WRONG. In English, you are "married to" someone, not "married with". This is a very common direct translation error.
Correct: "She has been married to her partner for ten years."
"listen music"
WRONG. You always "listen TO" something. The preposition "to" is obligatory with this verb.
Correct: "I love listening to music while I work."
"discuss about"
WRONG. "Discuss" already implies talking about something — the word "about" is redundant and incorrect.
Correct: "Let's discuss the proposal." (NOT "discuss about the proposal").
"I am at home since morning"
WRONG. The present perfect must be used with "since" in duration contexts, not the simple present or past.
Correct: "I have been at home since this morning."
"a interesting idea"
WRONG. Use "an" before words that begin with a vowel sound. The sound is what matters, not the spelling ("an hour", "a university").
Correct: "That is an interesting idea. It is also an unusual approach."
"go to the home"
WRONG. We say "go home" (no article, no preposition) or "go to someone's home". "Home" used as an adverb takes no preposition.
Correct: "I'm tired. I want to go home." / "Let's go to her home for dinner."
"in television"
WRONG. Use "on" for media and surfaces (on TV, on the radio, on screen, on the phone). Use "in" for enclosed spaces.
Correct: "I saw it on television" / "She appeared on the radio."
"I am knowing you"
WRONG. "Know", "like", "love", "want", "understand", "believe", and other stative verbs do not normally take the continuous form.
Correct: "I know you from somewhere." / "I understand the problem."
"did you went"
WRONG. In questions and negatives with "did", the main verb must be in the base form (bare infinitive), not the past tense.
Correct: "Did you go to the concert?" / "She didn't call me."
"I have seen him yesterday"
WRONG. The present perfect cannot be used with specific past time expressions like "yesterday", "last year", or "in 2010". Use the simple past.
Correct: "I saw him yesterday." / "I have seen him recently." (no specific time).
"When I will arrive, I call you"
WRONG. In time clauses beginning with "when", "after", "before", "until", and "as soon as", use the present simple — not the future.
Correct: "When I arrive, I will call you." / "I'll text you after I finish."
"she is working here since 2019"
WRONG. With "since" expressing an ongoing state from the past to now, English uses the present perfect (continuous), not the present simple.
Correct: "She has been working here since 2019."
"if I would know"
WRONG. In real conditionals (Type 1), use the present simple in the if-clause. In unreal conditionals (Type 2), use the past simple — not "would".
Correct: "If I knew the answer, I would tell you." (Type 2, unreal).
"I am living here for ten years"
WRONG. The present simple or continuous with "for" covering a period up to now requires the present perfect (continuous).
Correct: "I have lived here for ten years." / "I have been living here for ten years."
"He suggested to go"
WRONG. "Suggest" is followed by a gerund (-ing form) or a "that" clause — never by an infinitive.
Correct: "He suggested going out for dinner." / "He suggested that we go out."
"I am embarrassed (embarrassed ≠ pregnant)"
The Spanish/Portuguese "embarazada" means pregnant, not embarrassed. This is a classic false friend causing very awkward moments.
Correct: "I was embarrassed when I forgot his name." / "She is pregnant."
"eventually = finally (WRONG)"
"Eventually" means "at some point in the future, after a delay" — not "finally" in the sense of conclusion. Many European learners confuse this.
Correct: "He eventually found a solution." (after some time) vs "Finally, I would like to thank everyone." (conclusion).
"actual = current (WRONG)"
"Actual" in English means "real" or "genuine", not "current". From French "actuel" or Russian "актуальный" — a very widespread error.
Correct: "The actual cost was higher than the estimate." / "The current situation is improving."
"make a party"
WRONG direct translation. English uses "have a party" or "throw a party" — not "make a party". The verb collocates differently.
Correct: "We're throwing a party for her birthday." / "Are you having a party this weekend?"
"open the light"
WRONG direct translation (common from Semitic and Asian languages). Lights are "turned on" or "switched on", not "opened".
Correct: "Can you turn on the light, please?" / "She switched off the lamp before bed."
"sympathetic = nice (WRONG)"
"Sympathetic" means showing understanding or compassion for someone's problems — not simply "nice" or "friendly". A false friend from European languages.
Correct: "She was very sympathetic when I told her about my loss." / "He is a very friendly person."
"I assist to the meeting"
WRONG. "Assist" means to help. To attend an event, use "attend" or "go to". Confusion arises from French "assister à" or Spanish "asistir a".
Correct: "I attended the meeting." / "She assisted the manager with the report."
"he is very sympathique"
Inserting L1 words into English sentences when the false friend fails. "Sympathique" (French) / "simpático" (Spanish/Portuguese) = likeable/nice, not "sympathetic".
Correct: "He is very likeable." / "She is a really nice person to work with."
"its vs it's"
"It's" (with apostrophe) = "it is" or "it has". "Its" (no apostrophe) = the possessive pronoun. This is the single most common punctuation error in written English.
Correct: "It's a great idea." / "The company increased its profits last year."
"alot"
WRONG. "A lot" is always written as two words. "Alot" does not exist. Also note: "a lot" is informal — use "a great deal of" in formal writing.
Correct: "I have a lot of work to do this week." (informal) / "There is a great deal of evidence to consider." (formal).
"run-on sentences"
Joining two independent clauses with only a comma creates a run-on (comma splice). Use a full stop, semicolon, or coordinating conjunction instead.
WRONG: "The report was late, the manager was angry." CORRECT: "The report was late, so the manager was angry."
"I am looking forward to hear from you"
WRONG. After "look forward to", use a gerund (verb + -ing), not an infinitive. "To" here is a preposition, not part of the infinitive.
Correct: "I look forward to hearing from you." / "She is looking forward to starting her new job."
"Dear Sir/Madam, ... Best, [Name]"
Mixing formal opening ("Dear Sir/Madam") with casual closing ("Best") is a register mismatch. Formal letters use "Yours faithfully" (when you don't know the name) or "Yours sincerely" (when you do).
Correct: "Dear Sir/Madam, ... Yours faithfully," / "Dear Mr Smith, ... Yours sincerely,"
"however, + comma splice"
"However" is a conjunctive adverb — it cannot join two independent clauses with just a comma. Use a full stop before it or a semicolon.
WRONG: "The plan was good, however it failed." CORRECT: "The plan was good; however, it failed." / "The plan was good. However, it failed."
"I would like to inform you that..."
Overuse of this phrase makes emails verbose. In modern business English, directness is valued — state what you need to say without this preamble.
Instead of "I would like to inform you that the meeting is cancelled", write "The meeting on Thursday has been cancelled."
"would + present in academic writing"
Writing "this would suggest" when presenting your own research sounds overly tentative. Use "this suggests" or "the data indicate" for your own conclusions.
Weak: "The results would seem to show..." Strong: "The results show..." / "The data suggest..."
よくある質問
英語で最もよくある文法ミスは何ですか？
最も頻繁な文法ミスは：「I am agree」（動詞を形容詞として扱う）、三人称単数の-sを省略する（「he don't」）、時間表現での「for」と「since」の混同、「more better」のような二重比較級、そして「know」「understand」などの状態動詞に進行形を使うことです。これらのエラーはほぼすべての母語の学習者に見られます。
「make」と「do」はなぜ混同されるのですか？
多くの言語では「make」と「do」が一つの動詞に訳されるため（faire、hacer、machen、делать）、学習者はどちらを使うべきか迷います。一般的な規則として、「make」は作ったり生産したりするものに、「do」は活動や作業に使います。ただし、多くの表現は固定コロケーションで、暗記が必要です：make a decision、make a mistake、do homework、do your best。
英語の時制ミスを止めるにはどうすればよいですか？
最も効果的な戦略は、時制を孤立した形でなく文脈の中で学ぶことです。ミスが多い2つの対比に集中してください：(1) 過去形 vs. 現在完了形 — 現在完了形は「yesterday」や「last year」など完了した時間表現と一緒に使えないことを覚えてください；(2) 状態動詞での現在形 vs. 現在進行形。大量の本物の英語に触れることが、正しい時制使用を体に刷り込む最も実証されたアプローチです。
フォルスフレンドとは何ですか？なぜ危険なのですか？
フォルスフレンド（偽りの友、フォーセン・アミ）とは、2つの言語で見た目や発音が似ているが意味が異なる語のことです。見覚えがあるため学習者が根拠のない自信で使ってしまう点が危険です。よくある例：「actual」（英語：実際の；多くのヨーロッパ言語：現在の）、「eventually」（英語：いつか将来；欧州言語：最終的に）、「embarrassed」（英語：恥ずかしい；スペイン語・ポルトガル語：妊娠している）。最善策は自分の母語のフォルスフレンドリストを作ることです。
ネイティブスピーカーも同じミスをしますか？
はい — これらのミスの中にはネイティブスピーカーの文章でも非常によく見られるものがあります。「it's」と「its」、「their/there/they're」、文の区切りのないつながり（ランオン文）、カンマスプライスは、ネイティブのカジュアルな文章に定期的に登場します。違いは、ネイティブは知識不足ではなく不注意からミスを犯すことが多い点です。学習者にとって大切なのはルールを理解することですが、非公式な文章の規範は学術的・専門的な基準よりも緩いことも認識しておきましょう。
