Continuous verbs and gerunds end in "-ing" and have special spelling rules.
talk + ing
The -ing spelling rules are --
- add "-ing" to the verb.
- when a verb ends in "e", drop the "e" and add "-ing". For example: "take + ing = taking".
- when a one-syllable verb ends in vowel + consonant, double the final consonant and add "-ing". For example: "hit + ing = hitting".
- When a verb ends in vowel + consonant with stress on the final syllable, double the consonant and add "-ing". For example: "begin + ing = beginning".
- Do not double the consonant of words with more than one syllable if the stress is not on the final syllable. For example: "remember" has three syllables -- re:mém:ber -- and the stress is on the second syllable. Therefore do not add another consonant -- "remembering".
