THE -ING FORM

Remember that there are some rules to add -ing to the verbs:

* most of the times we just add -ing directly to the verb
          
          go ---> going                 work ---> working
          study ---> studying        play--->playing

* but when the verb ends in a silent final e preceded by a consonant, we drop the -e and add -ing

         live ---> living                write ---> writing

* when the verb ends in a consonant and it is a strong one syllable verb then we double the final consonant. Also when the verb has two or more syllables but the stress is on the last syllable.

        stop ---> stopping         begin ---> beginning
