* "-ing" is usually the ending of a present participle, which acts as a verb or an adjective. For example:
* "The running water" (adjective)
* "He is running" (verb)
* Some words ending in "-ing" can be used as adjectives, but they are not considered true adjectives. They are often called "participial adjectives" because they derive from verbs.
