Common mistakes when studying English, and how to fix them

After more than fifteen years teaching English in Egypt, Malaysia, Uruguay, Canada and online to professionals around the world, I have seen the same patterns again and again. Many learners study hard for years and still feel stuck. Usually, the problem is not intelligence or talent. It is a handful of common mistakes: in how they study, in how they think about learning, and in specific points of grammar, vocabulary and pronunciation. The good news is that every one of these mistakes can be fixed. This guide explains the most frequent errors I see and exactly what to do instead.

Part 1: Mistakes in how you study

1. Studying grammar but not speaking

Many learners can explain the rules of the present perfect perfectly, but freeze when someone asks them a simple question. Grammar knowledge is useful, but speaking is a skill, like swimming or driving. You improve by doing it. You would not learn to swim by reading about water.

Instead: speak every day, even for five minutes. Describe your day aloud, record voice messages, talk to yourself while cooking, join conversation classes. See building speaking confidence.

2. Waiting until you are "ready" to speak

"When my English is better, I will start speaking." This is one of the most common traps. You will never feel completely ready. Speaking is what makes you ready.

Instead: start now, at your current level. Mistakes are information that helps you improve, not proof that you are not good enough.

3. Studying a lot, but irregularly

Studying four hours on Saturday and nothing the rest of the week is less effective than fifteen minutes every day. Your brain needs frequent contact with the language to build memory and automatic responses.

Instead: build a small daily habit. I explain how in the daily English habit.

4. Learning words in isolation

Long lists of single words, "achieve, require, deadline, approach," are hard to remember and even harder to use. You may know the meaning but not how the word combines with others.

Instead: learn words in chunks and real sentences: "meet a deadline," "take a different approach," "achieve a goal." Write your own example sentences connected to your life.

5. Translating everything in your head

Translating word by word from your language slows you down and produces unnatural sentences. "I have 30 years" instead of "I am 30 years old" is a classic example for Spanish speakers.

Instead: learn complete expressions as units, and practice thinking in English with simple tasks: describe what you see, plan your day in English, answer questions quickly without preparing.

6. Only consuming, never producing

Watching series and listening to podcasts is excellent for comprehension, but passive exposure alone rarely creates fluent speakers. Many learners understand a lot and say very little.

Instead: balance input with output. After an episode, summarize it aloud or in writing. Use three new expressions in conversation.

7. Fearing mistakes and avoiding correction

Some learners avoid speaking because they are afraid of making mistakes, while others speak but never ask for feedback, repeating the same errors for years.

Instead: make mistakes freely, and ask a teacher or a fluent friend to correct the important ones. Focus on mistakes that affect understanding first.

8. No clear goal

"I want to improve my English" is too vague. Without a clear goal, it is hard to choose materials, measure progress or stay motivated.

Instead: set specific goals: "lead a ten-minute meeting in English by June," "pass a B2 exam," "order food and chat with locals on my trip." Know your level using the CEFR levels.

9. Using materials that are too easy or too difficult

If you understand everything, you are not learning; if you understand almost nothing, you will give up. The ideal material is challenging but understandable, where you know most words and can guess the rest from context.

10. Comparing yourself with others

Everyone learns at a different speed, depending on time, exposure, previous languages and life circumstances. Comparing yourself with a colleague or a social media influencer only creates frustration.

Instead: compare yourself with yourself six months ago. Record yourself speaking today and listen again in three months.

Part 2: Frequent grammar mistakes

These are the grammar errors I correct most often, especially with Spanish, French and Arabic speakers.

The present perfect deserves special attention; I explain it step by step in present perfect or past simple.

Part 3: Frequent vocabulary mistakes

False friends

Words that look similar in two languages but have different meanings cause many mistakes:

• Actually means "en realidad," not "actualmente" (currently).
• Assist means "help," not "attend."
• Embarrassed means "avergonzado," not pregnant.
• Library is "biblioteca"; a "librería" is a bookstore.
• Sensible means "sensato"; "sensible" in Spanish is "sensitive."

See the complete list in false friends between Spanish and English.

Make versus do

"Make a decision," "make a mistake," "make money," but "do homework," "do business," "do your best." Spanish uses hacer for all of them, so learners must memorize the combinations.

Say, tell, speak and talk

• Say something: "She said hello."
• Tell someone something: "She told me the news."
• Speak a language, or formally: "I speak English."
• Talk to or with someone, informally: "We talked for hours."

Phrasal verbs

Many learners avoid phrasal verbs and sound overly formal, saying "postpone" when colleagues say "put off," or "investigate" instead of "look into." Learning the most common ones makes your English sound much more natural. See 50 phrasal verbs for work.

Part 4: Frequent pronunciation mistakes

• Adding an "e" before "s" + consonant: "Espain," "estudent," "especial" instead of "Spain," "student," "special."
• Pronouncing every letter: English spelling is not phonetic. "Comfortable" sounds like "COMF-ta-ble," "Wednesday" like "WENZ-day."
• Ignoring word stress: stressing the wrong syllable can make a word unrecognizable. "deVELop," not "DEvelop."
• The -ed ending: "worked" is one syllable (/workt/), not "work-ed." Only verbs ending in t or d add a syllable: "wanted," "needed."
• Short and long vowels: "ship" and "sheep," "full" and "fool," "live" and "leave" are different words.
• The TH sounds: "think" and "this" use the tongue between the teeth.
• Final consonants: dropping the last sound changes meaning: "card" and "car," "rice" and "rise."

My pronunciation guide includes exercises for each of these.

Part 5: Mistakes in writing

• Very long sentences: English prefers shorter sentences than many Romance languages. If a sentence has more than 25 words, consider splitting it.
• Overly formal emails: "I am writing to inform you that…" can sound stiff. "Just a quick update on…" often works better. See business emails that sound natural.
• Capital letters: days, months, languages and nationalities take capitals in English: Monday, May, English, Colombian.
• Punctuation: no inverted question or exclamation marks at the beginning, and commas are used differently from Spanish.
• Not proofreading: reading your text aloud before sending catches many errors.

Part 6: Mistakes in mindset

"I'm not good at languages"

Everyone who speaks a first language is good at languages. Adults can learn very successfully; they simply need effective methods, regular practice and patience. Many of my most successful students started believing they were "bad at English."

"I need a perfect accent"

Your goal is to be understood clearly and comfortably, not to sound like a native speaker. Millions of fluent, successful English speakers have accents. Clarity matters more than accent.

"I studied for years and I'm still not fluent"

Often, those years included a lot of grammar and little speaking, or long breaks. A focused change in method can bring fast progress, even after years of frustration.

"I'm too old to learn"

I have taught adults of every age, including professionals in their sixties who reached new levels of confidence. Age changes how you learn, not whether you can learn.

Part 7: Mistakes in listening

Listening is often the skill learners neglect, yet it is the one that causes the most stress in real conversations. Common mistakes include:

• Trying to understand every word. Native speakers do not hear every word clearly either; they understand the general meaning and fill gaps from context. Focus on key words and the main idea.
• Only listening to slow, clear audio. Learning materials are useful at the start, but real English is faster, with reductions like "gonna" and "wanna." Gradually add authentic podcasts, series and interviews.
• Using subtitles in your language. They help you follow the story but not your English. Use English subtitles, then try without them.
• Listening only to one accent. If you only hear American English, a Scottish or Australian speaker may surprise you. Listen to a variety of accents, including non-native speakers, because international English is spoken by people from everywhere.
• Panicking when you do not understand. Asking for clarification is a skill: "Sorry, could you say that again?" or "Do you mean…?"

A 30-day plan to fix your most common mistakes

1. Days 1–3: record yourself speaking for two minutes about your day. Listen and write down the mistakes you notice, or ask a teacher to help.
2. Days 4–10: choose your three most frequent mistakes. Write five correct example sentences for each and read them aloud every day.
3. Days 11–20: speak at least ten minutes a day, paying special attention to those three points. Use voice messages, a conversation partner or classes.
4. Days 21–27: add one new skill: twenty minutes of listening a day with English subtitles, or a short daily paragraph in writing.
5. Days 28–30: record yourself again on the same topic as day 1. Compare. You will hear the difference.

Repeat the cycle with the next three mistakes. Small, focused improvements add up quickly.

A quick self-check

Answer yes or no:

1. Do I speak English at least a few minutes every day?
2. Do I have a specific goal with a date?
3. Do I learn expressions in context, not only single words?
4. Do I get regular feedback on my mistakes?
5. Do I use materials that are challenging but understandable?
6. Do I balance listening and reading with speaking and writing?

Every "no" is an opportunity. Change one habit at a time, and you will feel the difference within weeks.

How I help students avoid these mistakes

In my classes, I start by identifying each student's goals, level and recurring mistakes. We focus on real situations, such as meetings, travel, interviews and conversations, and practice speaking from the first minute. I correct the mistakes that matter most, explain them clearly and give you exercises to fix them. Above all, I create a relaxed environment where mistakes are welcome, because that is where learning happens. You can read about online learning in learning English online: how to get real results.

Remember: every fluent speaker you admire made these same mistakes once. The difference is that they kept practicing.

Be patient, be consistent and celebrate small wins.
