gas

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

'you talk' is the definition.
'gas' can be an answer for 'talk' (gas can mean to chat). I'm not certain of the 'you' bit.

'it's good when' is the wordplay.
'it's good' becomes 'g' (abbreviation).
'when' becomes 'as' (eg 'when I walked' means 'as I walked').
'g'+'as'='GAS'

Can you help me to learn more?

(Other definitions for gas that I've seen before include "Possibly noble" , "Chatter vapidly" , "idle chit-chat" , "Hydrogen or methane, say" , "Hydrogen, for example" .)

I've seen this clue in the Evening Standard.
