Today, we just use clever and cleverly (mainly). But we've had a few casualties along the way.

CLEVERABLE meant powerful in 19th century Derbyshire:

"I tak' it God Almighty's more cleverable and strong, nor all the devils put together."

In Scotland, CLEVERALITY meant Cleverness, ability.

"A man of no little cleverality in some things."

In the 19th century, it was hoped that CLEVERITY was going to replace cleverness:

"This word has with many persons supplanted cleverness."

Then the meaning of CLEVERLY wasn't fixed, either. It meant 'completely' in Cheshire:

"A building so dilapidated that it mun be pooddown cleverly."

I hope people still say 'pooddown' in Cheshire. It's CLEVERLY brilliant!
