Rooms close to pipe under home become gas-filled (7)
I believe the answer is:
inflate
'become gas-filled' is the definition.
I can't tell whether this definition defines the answer.
'rooms close to pipe under home' is the wordplay.
'rooms' becomes 'flat' (I've seen this before).
'close to' says to take the final letters (the close of something is the end).
'under' is a charade indicator (letters next to each other) (in a down clue, some letters go below others).
'home' becomes 'in' ('he's home' can mean 'he's in').
The final letter of 'pipe' is 'e'.
'flat'+'e'='flate'
'flate' put after 'in' is 'INFLATE'.
Can you help me to learn more?
(Other definitions for inflate that I've seen before include "Lean, fit (anag.)" , "Make bigger" , "Dilate" , "aggrandize them" , "Fill with gas" .)
