Identify the regular verb(s) given below:
A. Copy
B. Cut
C. Creep
D. Catch

Hint: The past tense and past participle of regular verbs are formed by adding the suffix ‘ed’ to them at the end; they follow simple rules of grammar. However for irregular verbs, the past and past participle changes the words altogether.

Complete step by step answer:
Option A – Copy: when changed into past tense the word copy becomes ‘copied’; the addition of ‘ed’ suffix changed its form but the word still remained the same. Hence this is the right option.
Option B – Cut: the present past and future forms of the word cut remain cut itself; hence this is not a regular verb and not the right option.
Option C – Creep: the past tense of this word is ‘crept’. The addition of ‘ed’ suffix is not possible here and it is an irregular verb. Hence this is not the right option.
Option D – Catch: the past tense of this word is ‘caught’, the addition of ‘ed’ suffix is not possible and the word itself took a different form. This makes it an irregular verb; hence it is not the right option.

So, the correct answer is “Option A”.

Note:
Regular verbs can be easily identified by adding the ‘ed’ suffix, if they do not fit into this syntax they automatically become irregular verbs.
