Why is the word occurrence final consonant doubled before suffix?

The word "occurrence" doesn't actually double its final consonant before a suffix. This is because the final consonant isn't doubled before a suffix unless it's stressed.

Let's break down why:

* Stress: The stress in "occurrence" falls on the first syllable ("oc"). The final consonant "e" is not stressed.

* Doubling Rule: The rule for doubling consonants before suffixes only applies to one-syllable words ending in a single consonant preceded by a single vowel, and when the final consonant is stressed.

Examples:

* "Occur" + "-ence" = "occurrence" (The final consonant is not stressed, so it is not doubled.)

* "Run" + "-ing" = "running" (The final consonant is stressed, so it is doubled.)

Therefore, the word "occurrence" does not double its final consonant because the final "e" is not stressed.
