What does tonsil mean?
Tonsil is the singular noun for one of the masses of lymphoid tissue at the back of the throat; tonsils usually refers to the paired palatine tonsils. These tissues belong to the immune system and help sample and defend against germs entering through the mouth and throat. The word is common in both general and medical English, especially in discussions of tonsillitis, swollen or enlarged tonsils, and tonsillectomy. Because the paired organs sit where the mouth meets the throat, they can become visibly enlarged during infection or other inflammation. Most people have tonsils from childhood, although surgery may remove them when recurrent infection causes substantial trouble. In ordinary use, tonsil usually means a palatine tonsil rather than the smaller lymphoid tissues associated with the nasal and tongue regions. The term therefore sounds particularly medical in diagnostic or surgical contexts, while everyday speakers commonly use it for the familiar pair at the back of the throat.
