Pedant is regularly spotted getting food (4)
I believe the answer is:
eats
'food' is the definition.
(eats is a kind of food)
'pedant is regularly spotted' is the wordplay.
'regularly spotted' indicates alternate letters.
'pedant'+'is'='pedantis'
The alternating letters of 'pedantis' are 'EATS'.
'getting' is the link.
(Other definitions for eats that I've seen before include "Takes food" , "fare" , "(Consumes) food" , "what is on the Christmas menu" , "Swallows food" .)
