والمتى: هو نسبة الشيء إلى الزمان.
Time is the relation of a thing or event to time.
The meeting took place in the morning — the event is related to a time.
The traveler arrived yesterday — a time is assigned to the arrival.
Ayn answers “Where?” and matā answers “When?”. The same event may happen “in the mosque” and “on Friday,” but the first is a spatial relation and the second temporal.
