1. Why Do Grammar Errors Happen?
Grammar errors are a natural part of learning any language. They usually occur because we translate directly from our mother tongue, or because we have not yet internalised the English sentence structure. For example, in Hindi we say “เคตเคน เคธ्เคूเคฒ เคाเคคा เคนै” which word‑for‑word is “He school goes”, so a learner might write “He school goes” instead of “He goes to school.” Common errors also arise from forgetting the rules of subject‑verb agreement, tense sequences, and the correct use of prepositions and articles. The good news: every error is fixable with awareness and practice. This post covers the errors that examiners most frequently mark as incorrect.
2. Subject‑Verb Agreement Errors
The verb must always match its subject in number and person. A singular subject takes a singular verb; a plural subject takes a plural verb.
- Wrong: The list of items are on the table. Right: The list of items is on the table.
(The subject is “list”, not “items”. “list” is singular.) - Wrong: Either my parents or my brother are coming. Right: Either my parents or my brother is coming.
(When two subjects are joined by “either…or”, the verb agrees with the nearer subject. Here, “brother” is nearer and singular.) - Wrong: The news are good. Right: The news is good.
(“News” is uncountable and always singular.)
3. Tense Errors
Learners often mix tenses or use the wrong form of the verb. Here are some classic mistakes:
- Wrong: I didn’t went to school yesterday. Right: I didn’t go to school yesterday.
(After “did not”, always use the base form of the verb.) - Wrong: She is knowing the answer. Right: She knows the answer.
(“Know” is a stative verb, not normally used in continuous tense.) - Wrong: I have finished my work yesterday. Right: I finished my work yesterday.
(Present perfect “have finished” is not used with a specific past time like “yesterday”; use simple past.)
4. Errors with Articles (A, An, The)
Articles are among the trickiest parts of English. Common errors include using “a” before a vowel sound, omitting “the” before unique things, and adding “the” before general plural nouns.
- Wrong: She is an university student. Right: She is a university student.
(“University” starts with a “yoo” consonant sound, so “a” is correct.) - Wrong: I saw dog on street. Right: I saw a dog on the street.
(General singular countable noun needs “a/an”; “street” is specific in context, so “the”.) - Wrong: The honesty is the best policy. Right: Honesty is the best policy.
(Abstract nouns used in a general sense take no article.)
5. Preposition Mistakes
Prepositions show relationships, and the wrong one can completely change the meaning or make the sentence ungrammatical.
- Wrong: He is good in mathematics. Right: He is good at mathematics.
- Wrong: We arrived at the airport on time. Right: We arrived at the airport on time. (Correct — “arrive at” for small places, “arrive in” for large ones. “arrive to” is always wrong.)
- Wrong: I am married with a doctor. Right: I am married to a doctor.
6. Word Order & Sentence Structure Errors
English follows a fairly strict Subject‑Verb‑Object (S‑V‑O) word order. Errors occur when learners place words in a sequence natural in their first language but incorrect in English.
- Wrong: She every day goes to school. Right: She goes to school every day.
(Time expressions usually go at the end.) - Wrong: The boy who is wearing a red cap he is my brother. Right: The boy who is wearing a red cap is my brother.
(Do not repeat the subject with a pronoun in the same clause.)
7. Miscellaneous Common Mistakes
- Confusing “there”, “their”, “they’re”
“There” = place; “their” = possession; “they’re” = they are. - Confusing “its” and “it’s”
“Its” = belonging to it; “it’s” = it is. - Double negatives: “I don’t know nothing.” → Right: I don’t know anything.
- Using “more better” or “most best” → Just “better” or “best”.
