bask

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

'lounge' is the definition.

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for bask that I've seen before include "Lie in the sun" , "Lie in warmth" , "Lie in sunshine" , "Soak up sun" , "Sun oneself (like a kind of shark?)" .)

I've seen this clue in The Independent.
