Informal girl, very stylish, at the King’s Head (5)
I believe the answer is:
chick
'informal girl' is the definition.
'chick' can be an answer for 'girl' (chick is a kind of girl). I'm unsure of the 'informal' bit.
'very stylish at the king's head' is the wordplay.
'very stylish' becomes 'chic' (similar in meaning. I am not sure about the 'very' bit.).
'at' says to put letters next to each other.
'head' suggests taking the first letters.
The initial letter of 'kings' is 'k'.
'chic'+'k'='CHICK'
Can you help me to learn more?
(Other definitions for chick that I've seen before include "Baby bird" , "Young bird" , "young singer" , "Young fowl" .)
