Common English Mistakes and How to Fix Them

The most frequent grammar errors include: confusing tenses (present perfect vs. past simple), wrong prepositions (I am interested in, not on), subject-verb agreement errors with uncountable nouns (Information is, not are), misuse of articles (the specific vs. a general), and incorrect word order in questions (What do you want? not What you want?).

These three words are homophones — they sound identical in speech. The confusion arises in writing because learners rely on phonological memory (how the word sounds) rather than orthographic memory (how it looks). Regular writing practice and targeted exercises like True or False help build the visual pattern recognition needed to use them correctly.

Proofread specifically for your known weaknesses. Use grammar checkers as a second pass (not a first). Create a personal error log — note each mistake, the correct form, and an example sentence. Review your error log before every writing task. This targeted approach is far more efficient than general grammar study.

Affect is usually a verb meaning to influence something: The weather affected our plans. Effect is usually a noun meaning the result: The effect was significant. The confusion is compounded by less common uses: effect can be a formal verb (to effect change = to bring about change) and affect can be a psychology noun. Memorise the most common pattern first: verb = affect, noun = effect.

Many languages lack an equivalent tense, so learners default to the past simple. The key distinction: use present perfect for past experiences with present relevance (I have visited London — my experience up to now) and past simple for finished past events with a specific time reference (I visited London in 2019). When in doubt, ask: is the time reference specific and finished, or general and connected to now?

Exercises like Complete the Sentence and Cloze Dropdown force you to produce the correct form, which builds stronger memory traces than passive reading. True or False tests whether you can identify correct grammar, while Quiz challenges recall of rules. Regular practice with immediate feedback trains automatic correct usage over time.

Grammarly and LanguageTool are the most widely used grammar checkers and catch most common errors. For academic writing, the British Council grammar reference is excellent. For exam preparation, past IELTS or Cambridge papers with answer keys teach you exactly where your knowledge has gaps. Use LexFizz exercises to fix specific weaknesses you identify.

Yes — repeating the same mistakes is very common and does not mean you are not progressing. Persistent errors are usually 'fossilised' — formed early and never properly corrected. To break the habit: identify the mistake precisely, understand the rule, create a strong correct example, and do targeted practice until the correct form becomes automatic.

The rule is based on sound, not spelling: use an before a vowel sound (an hour, an MBA, an umbrella) and a before a consonant sound (a university, a one-way street, a European). The letter itself does not determine the choice — the pronunciation of the first sound does. Exceptions catch many learners: an honest man (h is silent), a unique opportunity (u sounds like 'you').

Yes. Flashcards are highly effective for fixing vocabulary confusion (affect/effect, borrow/lend, make/do, say/tell). Create a card for each confusable pair with a clear example sentence showing correct usage. The Flash Cards exercise on LexFizz supports custom decks so you can build your own error-fix set.
