Have lunch with tenants occasionally (3)
I believe the answer is:
eat
'have lunch' is the definition.
'eat' can be an answer for 'lunch' (to lunch can mean to eat lunch). I am not sure about the 'have' bit.
'tenants occasionally' is the wordplay.
'occasionally' means one should take alternating letters.
The alternating letters of 'tenants' are 'EAT'.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for eat that I've seen before include "Munch" , "Partake of" , "Have 23d [MEAL]" , "Break bread" , "Bit, chew and swallow" .)
