Entertained English girl in brightly coloured clothing (7)
I believe the answer is:
regaled
'entertained english' is the definition.
'regaled' can be an answer for 'entertained' (I've seen this in another clue). I'm not sure about the 'english' bit.
'girl in brightly coloured clothing' is the wordplay.
'girl' becomes 'gal'.
'in' means one lot of letters goes inside another.
'brightly coloured clothing' becomes 'reed' (I can't justify this - if you can you should give a lot more credence to this answer).
'gal' placed within 'reed' is 'REGALED'.
Can you help me to learn more?
(Other definitions for regaled that I've seen before include "wined and dined" , "Feted" , "Plied with drink" .)
