Question

trimester Most women experience morning sickness in the first trimester of pregnancy. traɪˈmɛstər

Accepted Answer

(1) A period of about three months, especially one of three such periods in a human pregnancy. (2) One of three terms into which an academic year is sometimes divided. Semester, which comes from the Latin words for “six” and “month,” has come to mean half an academic year when the year is divided into two segments. When an academic year is divided into three segments, each is called a trimester (which is usually a bit more accurate, since each segment often is close to three months in length). Some colleges operate on the “quarter” system, with the summer being the fourth quarter, but this just means that each quarter is basically a trimester. In a human pregnancy, a trimester is three months long, representing one-third of the nine months that a typical pregnancy lasts
