What Are Inflectional Endings?

Inflectional endings are word endings added to a base word. They do not usually change the word’s part of speech, but they do change the meaning of the word.

For example:

dog + s = dogs, which means more than one dog

jump + ed = jumped, which means the action happened in the past

jump + ing = jumping, which means the action is happening now
