Initially, geese are laying specially for lasses (4)
I believe the answer is:
gals
'lasses' is the definition.
The answer and definition can be both people as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'initially geese are laying specially' is the wordplay.
'initially' indicates taking the first letters.
The initial letters of 'geese are laying specially' is 'GALS'.
'for' is the link.
Can you help me to learn more?
(Another definition for gals that I've seen is " Sloanes, say".)
