Etymology

LatinOld FrenchMiddle EnglishEnglish

This phrase joins office, a word for a place where professional work is done, with hours, a word for measured parts of the day. In modern English it first named the usual time when office staff are at work, and later also came to mean the fixed times when a teacher, doctor, or similar professional is available to meet people in an office.
