"Prepend" doesn't mean what you think it means

For years, I thought prepend text meant something similar to append text, accept it meant to add text to the beginning instead of the end of a word. Turns out that even though lots of other people seem to think the same thing, it actually means something else:

"Prepend" is a very obscure word which means literally to premeditate, as in, "He looked at her with malice prepended."
