Just born? Light gas and brew tea (7)
I believe the answer is:
neonate
'just born? light' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'gas and brew tea' is the wordplay.
'gas' becomes 'neon' (neon is a gas).
'and' is a charade indicator (letters next to each other).
'brew' is an anagram indicator.
'tea' with letters rearranged gives 'ate'.
'neon'+'ate'='NEONATE'
Can you help me to learn more?
(Other definitions for neonate that I've seen before include "One in delivery ward" , "New-born child" , "Recently born child" , "very young child" , "Young baby" .)
