This is the 1489th most frequent Japanese word.
駐
"駐" means "to stop," "to park," or "stationed" in the context of vehicles or positioning.
The word 駐 indicates 'parking' or 'stationing', used in the noun 駐車場 which means 'parking lot'.
駐車場に車を停めました。
I parked my car in the parking lot.
Here, 駐 is part of 駐在, meaning 'stationing or residing temporarily', indicating someone's assignment to a particular place.
彼は街に駐在しています。

In this case, 駐 is part of 駐留, referring to 'stationing or maintaining a presence', often in a military sense.
