verb spelling

Why is the verb "ripening" spelled with a single p?
Aren't we supposed to double the consonant for 1 vowel and 1 consonant ending verbs to make the -ing form?
Ex: stop--stopping

Not with long vowels. The rules about doubling are for short vowels. In American English, the rule is this:

Before adding most suffixes, double a consonant after a short vowel in one-syllable words or if the accent is on the final syllable in words of two or more syllables. Things are a bit different in British English, particularly with the consonant "L".

In BE, just double the final 'l' of as two-syllable word.

Is it only "L"? How about m, p, r, etc. ?
