Hi Shaimaa, they all mean being away from someone or something "Absent" is an adjective. Ex: The absent boy missed a great party. ("Absent" is describing "boy.") Ex: She was sad because the boy she likes was absent from class. ("Absent" is describing "boy.") "Absence" is a noun. Ex: Your absence is inexcusable. ("Absence" is serving as the subject of this sentence.) Absenteeism is also a noun Ex: The boss told me, " I don't appreciate your frequent absenteeism. One more day away and you're fired!" ("Absenteeism" is what you have done.)

Heh. Sneaky subtleties. Absence = the abstract concept Absentee = a person (the absent one, obviously) Absenteeism = the issue of people being absent.

Hmmmn...let me think! Give me a chance until the hereafter:)))))))

Haha! My own dictionary is on my hands now, I really can't understand the differences between these three words. They have the same meanings but I don't know what's the difference? Help me, teacher Arwa. :)))))
