One neat arrangement for a newly born (7)
I believe the answer is:
neonate
'a newly born' is the definition.
I can't judge whether this defines the answer.
'one neat arrangement' is the wordplay.
'arrangement' indicates anagramming the letters.
'one'+'neat'='oneneat'
'oneneat' is an anagram of 'NEONATE'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for neonate that I've seen before include "Recent arrival" , "produced baby" , "Being recently created" , "Young infant" , "very young child" .)
