have -- in Present Continuous | WordReference Forums

www.grammarly.com › blog › present-continuousThe present continuous (present progressive) tense is a way to convey any action or condition that is happening right now, frequently, and may be ongoing. It adds energy and action to writing, and its effect helps readers understand when the action is happening.
