Question

suffixes
complete ➔ completion
what happens when you add -tion to the
word complete?
a. it changes a verb into a noun.
b. it changes an adjective into a verb.
c. it changes a noun into a verb.
d. it changes a noun into an adjective.

Explanation:

First, analyze the word "complete" which can be a verb (meaning to finish) or an adjective (meaning whole). When we add "-tion" to get "completion", "completion" is a noun (referring to the act of completing or the state of being complete). Option a says it changes a verb (since "complete" can function as a verb) into a noun, which matches. Option b is wrong because "complete" as an adjective isn't turned into a verb by adding "-tion". Option c is wrong as "complete" isn't a noun first in this context of the transformation. Option d is wrong as it's not turning a noun into an adjective.

Answer:

a. It changes a verb into a noun.
