bright

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

'very clever' is the definition.
'bright' can be an answer for 'clever' (bright can mean clever or gifted). I am unsure of the 'very' bit.

I cannot understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for bright that I've seen before include "Clever; vivid" , "7 [CLEVER]" , "Clever - dazzling" , "bubbly?" , "Dazzling or intelligent" .)

I've seen this clue in The Irish Times.
