Somewhat caddish? One’s terribly given to fibbing (9)

I believe the answer is:

dishonest

I'm a little stuck... Click here to teach me more about this clue!

'to fibbing' is the definition.
I can't judge whether this defines the answer.

'somewhat caddish? one's terribly' is the wordplay.
'somewhat' indicates a hidden word.
'DISHONEST' can be found hidden inside 'caddish ones terribly'.

'given' acts as a link.

Can you help me to learn more?

(Other definitions for dishonest that I've seen before include "Bent" , "Untruthful - mendacious" , "Crooked" , "cheat" , "Fraudulent" .)

I've seen this clue in The Times.
