Charlie and son housed in modern arc-shaped road (8)
I believe the answer is:
crescent
'road' is the definition.
(thesaurus)
'charlie and son housed in modern' is the wordplay.
'charlie' becomes 'c' (phonetic alphabet).
'and' means one lot of letters go next to another.
'son' becomes 's' (genealogical abbreviation for son).
'housed in' indicates putting letters inside.
'modern' becomes 'recent' (I've seen this before).
's' placed into 'recent' is 'rescent'.
'c'+'rescent'='CRESCENT'
'arc-shaped' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for crescent that I've seen before include "Phase of the moon" , "Semi-circular shape" , "Growing" , "Muslim emblem" , "Turkish emblem" .)
