Have you ever caught yourself midway through an English sentence feeling that something sounded slightly unnatural, but you couldn't put your finger on what went wrong? You know grammar rules on paper, yet under the pressure of real-time speech, small habitual errors slip out.
The reassuring reality is that non-native speakers across the globe do not make thousands of random mistakes. They make the exact same dozen high-frequency slips over and over again. These errors rarely cause complete breakdown of communication, but eliminating them elevates your speech from awkward and hesitant to crisp, natural, and authoritative.
Below are 6 frequent English speaking mistakes, each with a clear 'Say This / Not This' formula and a practical explanation.
1. The 'Make' vs. 'Do' Trap
Creation vs. action and routine tasks
Many languages use a single verb (such as 'hacer', 'fazer', or 'machen') for both creation and physical action. In English, 'make' typically refers to producing, building, or causing an effect, while 'do' refers to actions, duties, and open-ended activities.
| Use 'MAKE' For | Use 'DO' For |
|---|---|
| Make an appointment / a call | Do business / do research |
| Make a suggestion / an offer | Do your best / do your duty |
| Make money / a profit | Do the dishes / do laundry |
| Make sense / make an impression | Do harm / do good |
Make vs. Do in Action
Explanation: Decisions, mistakes, and calls are created (make); homework, chores, and favors are actions (do).
2. The Bored vs. Boring Confusion (-ed vs. -ing Adjectives)
Inner emotional states vs. external characteristics
Few slips cause as much unintended amusement in social settings as mixing up participial adjectives. Saying 'I am so boring' tells the listener that you are a dull, uninteresting person, when what you meant to express was 'I am bored' (your internal feelings).
- Interested (how you feel) vs. Interesting (the topic provoking interest).
- Confused (your mental state) vs. Confusing (the complex explanation).
- Fascinated (captivated by a subject) vs. Fascinating (the captivating subject).
Participial Adjective Contrast
Explanation: Things that cause the feeling end in '-ing'; people who experience the sensation end in '-ed'.
3. Preposition Traps: In, On, and At for Time and Place
Visualizing prepositions as an inverted pyramid
Prepositions feel arbitrary because they cannot be translated word-for-word. The easiest mental model is the inverted pyramid: move from the broadest, most general container down to the most specific pinpoint.
| Preposition | Time Dimension | Location Dimension |
|---|---|---|
| IN (General / Large) | Centuries, years, months: 'in 2026', 'in July' | Countries, cities, enclosed rooms: 'in London', 'in the kitchen' |
| ON (Specific / Surface) | Days and dates: 'on Monday', 'on May 4th' | Streets, surfaces, transit: 'on Oxford Street', 'on the bus' |
| AT (Pinpoint / Precise) | Exact clock times: 'at 9:30 AM', 'at noon' | Exact addresses, point locations: 'at 42 Wall Street', 'at the station' |
4. Dropping or Adding Third-Person Singular '-s'
The reflex that disappears when speaking under pressure
Every intermediate learner knows that 'he/she/it' requires an '-s' in the present simple. Yet in fast-paced conversations, people frequently say 'He work at Stripe' or conversely overcompensate with 'Can she comes today?'
Modal Verbs and Third Person
Explanation: Modal verbs (must, can, should, would) are always followed by the base infinitive without '-s'. In negatives, use 'doesn't', not 'don't'.
5. 'Explain Me' vs. 'Explain to Me'
Ditransitive verbs vs. prepositional requirements
In many languages, verbs like 'explain', 'suggest', and 'describe' take an indirect pronoun directly. In English, you cannot say 'Explain me the plan'—you must say 'Explain the plan to me' or 'Explain to me what happened.'
Sample dialogue
"Hey, can you explain me how the authentication service works?"
"Sure, let me explain the architecture to you over a short screen share."
6. 'I Have 30 Years' and Age Formulations
State of being vs. possession
In Romance, Germanic, and Slavic languages, age is frequently possessed. In English, age is a continuous state of existence described strictly with the verb 'to be'. Saying 'I have 28 years' sounds like you are holding twenty-eight years in a suitcase.
Age Expression
Explanation: Use 'is [number] years old' (or simply 'is [number]'). Use 'for' to measure duration, not 'since'.
Frequently asked questions
Why do I keep making these mistakes even though I know the grammar rule?
Knowledge stored in conscious declarative memory requires time to access. In spontaneous speech, your subconscious motor reflexes take over, reverting to your native language's syntax. Only vocal repetition builds speech automaticity.
Is it bad to pause and correct myself when I notice a mistake?
A quick, seamless self-correction ('He go—he goes to the office') shows high linguistic awareness. However, constantly restarting sentences destroys conversational flow. Fix it once and keep moving forward.
How can I test my speech for these specific errors?
Record yourself answering a mock question for 2 minutes and check your transcript against this list. You can also rehearse speaking with Mivo in Spekvia, which points out mistakes during the conversation.
Mistakes are not signs of intellectual failure; they are natural cognitive artifacts of your brain mapping two distinct linguistic operating systems. Every seasoned speaker has walked through the exact same phase.
Pick just two mistakes from this guide today—perhaps 'make vs. do' and 'in/on/at'—and focus consciously on them during your next conversation or practice session. Once those become second nature, move to the next pair.
Precision in spoken English is built one corrected habit at a time.
