Smacks, or possibly nips (6)
I believe the answer is:
tastes
This could be a double definition.
'smacks' is the first definition.
The definition and answer can be both acts as well as being plural nouns.
Maybe there's an association between them I don't understand?
'possibly nips' is the second definition.
Although both the answer and definition are verbs in their -s form, I cannot understand how they can define each other.
'or' is the link.
Can you help me to learn more?
(Other definitions for tastes that I've seen before include "Eats a sample of" , "Flavours or penchants" , "Tries to determine the flavour of" , "Samples the flavour of" , "Relishes or penchants" .)
