Use of Et cetera

- "Et cetera" is Latin and is usually abbreviated as "etc." It’s used for two reasons: when the omitted material is obvious, and when additional information is unnecessary.

- When used at the end of a sentence, it is preceded by a comma and followed by a period.

I have all the necessary items to make a cake, like flour, sugar, etc.
You’ll find tissues in the bathroom, living room, kitchen, etc.

- If the et cetera (etc.) appears in the middle of a phrase it is followed by both the period it always keeps as well as a comma.

I ate so much chocolate, fudge, cake, etc., that I gave myself a stomach ache.
