One inclined to make a retreat (5)

I believe the answer is:

bower

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

'a retreat' is the definition.
(I have seen 'Shady retreat' mean 'bower' so perhaps 'retreat' could also mean 'bower')

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for bower that I've seen before include "Shaded place under trees" , "lady's private room?" , "sanctuary" , "Shady retreat" , "Shady garden place" .)

I've seen this clue in The Times and The Sunday Times.
