Same sounds occurring intermittently for years (5)
I believe the answer is:
aeons
'years' is the definition.
The definition and answer can be both related to time as well as being plural nouns.
Maybe there's a link between them I don't understand?
'same sounds occurring intermittently' is the wordplay.
'occurring intermittently' means one should take alternating letters.
'same'+'sounds'='samesounds'
The alternating letters of 'samesounds' are 'AEONS'.
'for' is the link.
Can you help me to learn more?
(Other definitions for aeons that I've seen before include "Vast ages" , "Long periods of time" .)
