See porky in undergarment? Extremely far from ugly (9)
I believe the answer is:
loveliest
'extremely far from ugly' is the definition.
I can't tell whether this defines the answer.
'see porky in undergarment?' is the wordplay.
'see' becomes 'lo' (archaic exclamation meaning 'look!').
'porky' becomes 'lie' (I've seen this in other clues).
'in' is an insertion indicator.
'undergarment?' becomes 'vest' (vest is a kind of undergarment).
'lie' put into 'vest' is 'veliest'.
'lo'+'veliest'='LOVELIEST'
Can you help me to learn more?
(Other definitions for loveliest that I've seen before include "Most charming" , "Prettiest" , "most beautiful" .)
