-ing is an English language suffix used primarily in two closely related ways:

• As a verb form (the present participle), to indicate the continuous aspect, as in "I am learning about English grammar" see Continuous and progressive aspects
• As a corresponding noun, as in "Learning is fun", where it is known as the gerund see Gerund

It is also used more rarely in various other ways see Wiktionary article on "-ing" for details; these include:

• Uncountable collective nouns, such as piping
• Having a quality, as in gelding
• Patronymics, as in Browning

Certain English language dialects are characterized in part by the omission of the final "g" in the pronunciation of words ending in -ing. This may be denoted in eye dialect writing with the use of an apostrophe, with, for example runnin' used in place of running.
