Making English nouns plural can be confusing. “Count” nouns refer to things that can be counted and made into plurals (a hundred dollars, six miles, three children). “Noncount” nouns refer to things that cannot easily be counted (money, wisdom, love, traveling); these usually have no plurals.
Noun error: The box contained many photo of my family.
Correct: The box contained many photos of my family
Noun error: We have ordered new office equipments.
Correct: We have ordered new office equipment.
The articles a, an, and the signal that a noun will follow. A and an are used in front of nonspecific, singular count nouns (a movie, a cat, an octopus, an advertisement). The is used in front of specific singular and plural nouns (the movie, the cats, the furniture, the future). But be careful: many noncount nouns require no article at all.
Article error: There was beautiful sunrise this morning.
Correct: There was a beautiful sunrise this morning.
Article error: The martial artists bowed to each other to show the respect.
Correct: The martial artists bowed to each other to show respect.
Error #3: Preposition Error
Many expressions in English contain prepositions, which can easily confuse the non-native speaker. Tip: memorize common expressions containing prepositions.
Preposition error: On March, we will go to the mountains.
Correct: In March, we will go to the mountains.
Preposition error: Joaquin is acquainted to the president.
Correct: Joaquin is acquainted with the president.
Other examples of errors with prepositions:
We discussed about his plan.
My sister married with a foreigner.
This table is made by wood.
Yesterday I went to shopping.
Error #4: Repeated Subject
The subject of a sentence should not be repeated in pronoun form.
Repeated subject: My engineering professor she is very smart.
Correct: My engineering professor is very smart.
Error #5: Wrong Verb Tense
Make sure your verbs reflect the correct tense (time)-present tense, past tense, and so forth. Study and practice will help you master the verb tenses in English.
Tense error: Yesterday, I cash the refund check and buy a laptop.
Correct: Yesterday, I cashed the refund check and bought a laptop.
Tense error: The Arteaga brothers wait here for two hours.
Correct: The Arteaga brothers have waited here for two hours.
Error #6: Irregular Verb Errors
Regular verbs in English end in –ed in both the past tense and past participle (work/ worked, has worked), while irregular verbs often change form (take/ took, has taken). For non-native speakers, the best way to learn irregular verb forms is to memorize them.
Verb error: Lee cutted fabric for the vests.
Correct: Lee cut fabric for the vests.
Verb error: They all have went to the film festival.
Correct: They all have gone to the film festival.
Error #7: Wrong Form After a Verb
Some verbs in English can be followed by an –ingverb form; in many such expressions, a preposition falls between the main verb and the -ing form: He believes in working hard. Other verbs (for example, decide, have, agree, and plan) must be followed by an infinitive (to + the main verb). Don’t use an infinitive where an –ing verb is needed—or vice versa.
Wrong verb form: We enjoy to eat there.
Correct: We enjoy eating there.
Wrong verb form: The pilot wanted landing in Dallas.
Correct: The pilot wanted to land in Dallas.
Error #8: Wrong Order of Adjectives
ESL writers need to pay special attention to the order of adjectives. In English, when two or more adjectives (modifiers) appear before a noun, they should follow a certain order. Here is the usual order of adjectives in a series:
Article or other noun signal word (a, an, the, most)
2. Judgment (wonderful, unfair, useful, ugly)
3. Size (large, tiny, little)
4. Shape (round, long, bell-shaped)
5. Age (old, teenaged, modern)
6. Color (green, yellow, black)
7. Nationality (Vietnamese, Dominican, Russian)
8. Material (stone, wood, cotton)
Wrong adjective order: I just bought a yellow new Mini Cooper.
Correct: I just bought a new yellow Mini Cooper.
Wrong adjective order: Is that your silver Mexican favorite necklace?
