Wordly Wise

Fascinating! From the Word Origin Calendar.

MOOCH
In Old French, the verb muchier meant "to hide" or "to lurk." The English version appeared in the 1800s, but it was first used to mean "to sneak" or "to be truant," before the meaning evolved to a different sense, "to beg."

FORGIVE
The Latin compound word perdonare is formed from per-, meaning "thoroughly" and donare, meaning "to give." In Old English, both parts of this word were swapped for their English counterparts, for-, meaning "completely," and giefan, meaning "give," creating a new term matching the original in meaning.
