What to open for a breath of air at the town centre (6)
I believe the answer is:
window
'air at the town centre' is the definition.
I can't judge whether this definition defines the answer.
'what to open for a breath of' is the wordplay.
'to open' says to take the initial letters (I've seen 'opens' mean this).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'a breath' becomes 'wind' (wind is a kind of breath).
'of' becomes 'o''.
The initial letter of 'what' is 'w'.
'wind'+'o'='windo'
'w' after 'windo' is 'WINDOW'.
Can you help me to learn more?
(Other definitions for window that I've seen before include "Glass-filled opening" , "Glass aperture" , "time still available" , "Eg, oriel or fanlight" , "Opening (of opportunity?)" .)
