English verbs have five basic forms:

1.If a verb ends in a stressed vowel + one or more consonants + e or ue, "drop" the e and add - ing.

Examples: save / saving;

2.If a verb ends in - ie, change the - ie to - y and add - ing.

Examples:die / dying; lie / lying;

3.If a verb ends in y, add - ing. It doesn't matter if there is a vowel or a consonant before y.

Examples: pry / prying pray / praying

4. If a verb ends in a vowel + one consonant,double the consonant and add - ing.

Examples:beg / begging; chat / chatting

the r: just add - ing:

súffer / suffering

6.If a verb ends in a vowel, add - ing.
