Eggs some Geordies sent round (3)
I believe the answer is:
roe
'eggs' is the definition.
(fish eggs)
'some geordies sent round' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'sent round' says the letters should be written backwards.
'eor' is hidden in the letters of 'geordies'.
'eor' backwards is 'ROE'.
(Other definitions for roe that I've seen before include "Part of fish, sounds like go through water" , "Fish eggs; small deer" , "Caviar" , "Swift runner" , "Hoofed animal(s)" .)
