Question

Choose the correct option to replace the word(s) given in brackets:

(Err) is human.

• A. Err to
• B. Erring to
• C. To erring
• D. To err

Answer 1

Answer: (D)

To err

The infinitive verb is a verb with the word 'to' in front of it. This verb is always just a verb. There is no - ed, no - ing, no - s at the end of the verb. Here, the infinitive verb is used as a subject of the sentence. Thus, options A, B and C are wrong according to the rule. The correct option is D since 'to' is used as subject of the sentence. Hence, sentence would become: To err is human.
