What it means
ている follows a verb's て-form to describe an action that is currently in progress or a condition that continues. It is commonly translated as “be doing,” but with some verbs it describes a resulting state, such as being married or knowing something. The familiar form ends in ている, while the polite form ends in ています.
Usage note
With verbs that describe a change or a lasting condition, ている may describe the resulting state rather than an action in progress. The exact meaning depends on the verb and context.
