Question

Do as directed: 5. Write two present participles in which the last letters are doubled.​

Answer 1

We add -ing to a verb to form its present participle, and -ed to regular verbs to form the past simple. When doing this, we sometimes double the last letter of the verb, as in these examples:

stop ⇒ stopped, stopping
stoped
stoping
refer ⇒ referred, referring
refered
refering
Sometimes, however, we don’t double the last letter, as with the verb visit:

visit ⇒ visited, visiting
visitted
visitting
