I am not sure what comes to mind for you when you hear someone talk about T & A, but for me, sadly, it is none too wholesome.
Today I heard it no less than 5 times. Only the context saved me. It was in a consult with an ear, nose, and throat doctor. For an ENT, T & A means tonsil and adnoid.
At the same time, I couldn't help but force back my snicker when the nurse said "T & A" with a completely straight face.
