Questions & Answers about אם יום חמישי לא מתאים לך, ניפגש מחרתיים אחרי העבודה.
אם means if in this sentence.
It introduces a condition:
אם יום חמישי לא מתאים לך...
= If Thursday doesn’t work for you...
Hebrew also uses אם to mean whether in other contexts, but here it is clearly conditional: if.
In Hebrew, the days of the week are often named with יום + a number/order word.
So:
- יום ראשון = Sunday
- יום שני = Monday
- יום שלישי = Tuesday
- יום רביעי = Wednesday
- יום חמישי = Thursday
Literally, יום חמישי is something like fifth day.
In casual speech, people sometimes shorten it and just say חמישי, but the full form יום חמישי is completely normal and very common.
