When adding the “-ing”, we have to follow special spelling rules. The general rule is to add -ing to the verb. For example, for verbs like wait, visit, speak, add only -ing (i.e., wait ing; visit ing, speak ing.) When a verb ends in a silent e, we drop the e and add -ing. For example, clos e becomes clos ing.

Adding '-ing' creates an extra syllable to the word. If the root word ends in a consonant + 'e', the 'e' is removed before the suffix is added. If the root word has a short vowel and ends in a consonant, the consonant is doubled before the suffix is added.

The general rule is to simply add 'ing' to the base verb, i.e. talk becomes talking and sing becomes singing. If the verb ends in an 'e', you simply need to remove it. For instance, dance becomes dancing. If it ends in 'ie', the ie becomes a y. For example, lie becomes lying.

When -ing is added to the end of a word, it can show the past tense or the present tense. If the root word has a short vowel and a single consonant, the consonant letter is doubled when the suffix is added. If the verb ends in a "y", just add "-ing".

A suffix is a letter or group of letters at the end of a word which creates another word. Adding "-ing" creates an extra syllable to the word. If the root word ends in the consonant "e", the "e" is removed before the suffix is added.
