A suffix is a specific ending that can be added to a number of words. The original section to which the suffix becomes attached is known as the stem. Common suffixes include -ed and -ing. These characterize what place in time the actions are occurring (i.e. past or present). If a word ends in -ing, such as running, that means that it is currently happening in the present. If a word ends in -ed, this is past tense and means that the action previously happened.
