"Waiting" can be expressed as "to wait" in Engpsh.

This phrase is a verb that comes from Old Engpsh "wæccan," meaning "to stay awake." Over time, the meaning evolved to include "to be in readiness or expectation," and eventually came to mean "to stay in one place until a particular time or until something you are waiting for happens."
