Unknown(or spelling error) words and proper nouns are highlighted in green.
Grammatical error words are highlighted in red. TwinMarker typically checks the following errors:
The Agreement of Subjects and Verbs: checks for the third person singular present form of verbs.
- The subject is third-person singular, but the verb is in the present tense and doesn't take the –s inflection.
- Example: He drive the car.
- Example: Your desire for success have to be greater than your fear of failure.
- The subject is not third-person singular, but the third-person singular verb is used.
- Example: I drives the car.
- The subject is third-person singular, so the verb be should be used in the form 'is' or 'was'.
- Example: The car which we bought were very expensive.
Determiner Usage: checks for redundant determiners, the order of determiners, and the combination of determiners and nouns.
- These determiners shouldn't be used together when qualifying the same noun.
- The determiner order is wrong.
- This determiner should be used with singular nouns only.
- This determiner should be used with plural nouns only.
- The indefinite article should be used depending on the initial sound of the following word.
The Combination of Verbs and Objects:
- The verb cannot take an infinitive as object.
- Example: I finished to clean the room.
- The verb cannot take an -ing form as object.
- Example: I decided selling the house.
- You should probably use the word 'should' or the subjunctive present form in the objective clause of the verb.
- Example: He desired that his son returned to Tokyo.
- You should use the subjunctive form in the objective clause of the verb 'wish'.
- Example: I wish I am a doctor.
The Other Word Usage:
- abroad: The word 'abroad' functions as adverb, so the word 'to' is not needed.
- seem: The verb 'seem' cannot be used in passive voice.
