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

'more or less' is the definition.
(I've seen this before)

(Other definitions for roundabout that I've seen before include "It's not exactly" , "More or less" , "Circuitous" , "Roughly" , "fun for children" .)

I've seen this clue in the Evening Standard.
