Incorrect spelling

becomming

Incorrect spelling, explanation: becomming is a mistaken spelling, because there is no reason to double m when we add suffix -ing. In the base verb become the last letter is e, not m, so the consonant can’t double, however e is skipped (as usual in case of -ing suffix) and we receive the form becoming. Therefore the correct spelling is becoming.


Correct spelling

becoming

Correct spelling, explanation: this word should be spelled with one m because the base verb become ends with e. This vowel is skipped in case of adding -ing ending (giving us the form becoming), but m isn’t doubled, because it’s not at the end of the word. Therefore becoming is the correct form, and becomming is a mistake.
