To spell the word occurrence, why is the final consonant doubled before adding the suffix?

Question

because the base word ends with two vowels before the final consonant

because the stress is on the second syllable of the base word ending in consonant + vowel + consonant

because the suffix begins with a consonant

because the base word ends in two consonants

Answer 1

The correct reason for doubling the final consonant in the word "occurrence" before adding the suffix is:

because the stress is on the second syllable of the base word ending in consonant + vowel + consonant.

In this case, the base word "occur" has the stress on the second syllable, which is why the final consonant 'r' is doubled before adding the suffix "-ence."
