School members record greeting among fellows (8)
I believe the answer is:
dolphins
'school members' is the definition.
Although both the answer and definition are plural nouns, I can't see how one could define the other.
'record greeting among fellows' is the wordplay.
'record' becomes 'L-P' (abbreviation for long play record).
'greeting' becomes 'hi' (hi is a kind of greeting).
'among' indicates putting letters inside (inserted letters are placed among others).
'fellows' becomes 'dons'.
'lp'+'hi'='lphi'
'lphi' going inside 'dons' is 'DOLPHINS'.
Can you help me to learn more?
(Other definitions for dolphins that I've seen before include "Beasts" , "Small sociable whales" , "sea creatures" , "Gregarious, friendly mammals" , "Aquatic mammals" .)
