Grammar mistakes EFL writers keep making

I've spent years watching non-native English writers trip over the same grammar mistakes. The patterns are predictable, and the fixes are more straightforward than most people expect. Full disclosure: I built BeLikeNative, a free Chrome extension for real-time grammar and writing help. Take my perspective accordingly.

The three errors that keep showing up

Research on EFL writing points to three grammar categories that account for most mistakes. Verb tense errors top the list at about 14% of all errors. Article misuse and preposition confusion follow close behind.

These aren't random. They're predictable based on a writer's first language.

Verb tenses and why they stick

English has a lot of tense forms. Perfect, continuous, simple, and combinations of all three. If your native language doesn't distinguish between "I ate" and "I have eaten," you'll default to whichever feels closest.

I've seen this pattern repeatedly with writers whose L1 has a simpler tense system. They pick one past form and use it everywhere. The fix isn't memorizing conjugation tables. It's reading enough English that the right form starts to sound right.

Articles are the quiet problem

"A," "an," and "the" seem trivial. They're not. If you speak Chinese, Russian, Japanese, or any language without articles, you're essentially learning a concept that doesn't exist in your thinking.

As researcher Huei-Chun Yuan put it, EFL learners often unconsciously carry their L1 patterns into English sentence production. That's exactly what happens with articles. Writers either drop them entirely or scatter them where they don't belong.

I don't think there's a shortcut here. Reading helps. So does getting corrected in context, not through fill-in-the-blank exercises.

Prepositions and the "close enough" trap

A corpus study flagged ten prepositions that get misused constantly: by, at, in, to, for, on, about, of, with, and as. Chinese learners, for example, often mix up "in," "on," and "at" because their language uses a single term for concepts that English splits across multiple prepositions.

The research suggests teaching prepositions through collocations (pairing them with words they naturally go with) rather than as isolated rules. That matches my experience. Learning "interested in" as a unit works better than memorizing that "in" means "inside something."

Finding your own patterns

There are two broad approaches to tracking grammar errors, and the best results come from combining both.

Data tools like AntConc and Wordsmith can process large volumes of writing and surface patterns you'd never catch manually. One study ran 1,040 essays through Wordsmith and found 8,691 errors across 339,040 words. About 16% were cohesion problems. Another 14% involved articles and determiners.

But automated tools miss context. Hand-marking errors still matters. Among Level 2 EFL learners, misselection (picking the wrong word) accounts for nearly half of all mistakes at 48%. Omission follows at 29%, and overinclusion at 14%.

The practical move is to keep an error log. Write down what you get wrong, look for clusters, and focus your practice there. Most writers have three or four error types that make up the majority of their mistakes.

What actually fixes these errors

I've tried a lot of approaches over the years. Here's what I've seen work.

Grammar check tools catch surface-level mistakes fast. BeLikeNative supports over 80 languages and gives contextual suggestions while you write. It handles agreement errors, run-on sentences, and punctuation without you having to leave whatever platform you're on. That immediate feedback loop matters because you learn the correction at the moment you made the mistake.

But tools alone won't get you there. Self-correction builds the deeper skill.

Keep a log of recurring errors. Partner with other learners for peer review. Research shows that peer feedback helps L2 learners recognize their own strengths and weaknesses while pushing them to collaborate and negotiate meaning with each other. Fresh eyes catch things you'll miss every time.

The biggest shift I've seen comes from practicing grammar inside real writing tasks, not isolated drills. Studies back this up. Isolated grammar exercises don't reliably transfer to better writing. What works instead: short, focused grammar lessons tied to actual writing problems, one-on-one feedback on specific errors, and reading extensively to build an intuitive feel for how English works.

Grammar in context beats grammar in isolation

One quote from the research stuck with me. Hyland argues that linguistic forms are complex and their functions can't be identified in a social and textual vacuum. That's a formal way of saying you learn grammar by using it, not by studying it in the abstract.

So if you're an EFL writer trying to improve, start with your own errors. Track them. Look for patterns. Use a tool to catch what you miss in real time. And read as much English as you can stand. The combination of awareness, feedback, and exposure is what actually moves things forward.
