Gaped around, so loveless, as one panted! (6)
I believe the answer is:
gasped
'one panted' is the definition.
(I've seen this before)
'gaped around so loveless' is the wordplay.
'around' means one lot of letters goes inside another.
'so loveless' becomes 's' (I am not sure about this - if you are sure you should believe this answer much more).
'gaped' placed around 's' is 'GASPED'.
'as' is the link.
Can you help me to learn more?
(Other definitions for gasped that I've seen before include "Drew in breath sharply, as in surprise" , "Breathed noisily" , "Drew breath in sharply as in astonishment" , "Breathed laboriously" , "'Panted, puffed (6)'" .)
