Randy reveller attending second year's gathering (5)
I believe the answer is:
satyr
'randy reveller' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'attending second year's gathering' is the wordplay.
'attending' becomes 'at' (e.g. at school means attending school).
'second' becomes 's' (common abbreviation).
'year' becomes 'yr' (abbreviation).
'gathering' is an insertion indicator (gather can mean to acquire or bring in).
's'+'yr'='syr'
'at' going within 'syr' is 'SATYR'.
Can you help me to learn more?
(Other definitions for satyr that I've seen before include "Forest god - old goat" , "Woodland deity - lustful man" , "Mythical woodland god or grossly lustful man" , "Lustful woodland god -- stray (anag)" , "Lecherous god" .)
