The suffixes -ed, -ee, -ing, and -ment can be added to the end of the word commit.

Question

For which of the following do you not need to double the final consonant before adding the suffix?

commit + -ee

commit + -ing

commit + -ed

commit + -ment

Answer 1

You do not need to double the final consonant before adding the suffix -ment (commit + -ment = commitment).

For the other suffixes:

• commit + -ee results in "committee" (double the 't').
• commit + -ing results in "committing" (double the 't').
• commit + -ed results in "committed" (double the 't').

So, the correct answer is commit + -ment.
