CARING ABOUT CARET

You all know what a caret is, but only few of you know the word for it. A caret is the carrot-shaped symbol used to denote exponents or to make editorial changes (^), not to be confused with a circumflex. Since the caret was used for the latter purpose much longer than the former, the word comes from the Latin term caret, or "there is lacking". When a caret was added to put in more words, that statement was acknowledged as implied. This is a conjugated form of carere, or "to lack", which reportedly stems from the Proto-Italic cognate kazeo, ultimately from the familiar Proto-Indo-European root kes, or "to cut". The aforementioned Latin word carere, by the way, is also the source of the word caste, through castus, "separate in a pure way". The word caret should also not be confused with the caret package, a programming term which is the acronym for Classification and Regression Training. Those last two facts should've been added by caret.
