His other daughter started as an attractive girl (4)
I believe the answer is:
dish
'an attractive girl' is the definition.
(I've seen this in other clues)
'his other daughter started' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'his' is 'ish' which is within the answer.
'daughter' could be 'd' (genealogical abbreviation) and 'd' is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'as' acts as a link.
Can you help me to learn more?
(Other definitions for dish that I've seen before include "Cooking vessel" , "bit of pottery?" , "Directional antenna -- good-looking woman or man" , "course" , "Attractive person" .)
