Karat or karat ( kar at ) is a measure of the quality of gold--
If the gold is 12 karat, it is half gold and half something else, such as silver.
Gold that has nothing mixed with it is marked 24 karat gold.

Caret or caret  ( kar et ) means the small triangular mark used to show where a word or phrase should be inserted in a sentence--
If you leave out a word while typing, you can use a caret ( ^ ) to show where it belongs.
Type a caret between the two words where you mean to add a correction.
