Should the t in accept be doubled before suffix ing is added?

No, the "t" in "accept" does not double before adding "-ing."

Here's why:

* The rule: You only double the final consonant before adding "-ing" if the word has:

* One syllable

* Ends in a single consonant

* Is stressed on the last syllable

* Accept doesn't fit the rule: "Accept" has two syllables ("ac-cept") and the stress is on the second syllable.

Therefore, the correct spelling is accepting.
