Likely place to find Christmas greetings (2,3,5)
I believe the answer is:
on the cards
'likely' is the definition.
(I've seen this before)
'to find christmas greetings' is the wordplay.
I cannot really understand how this works, but
'greetings' could be 'cards' (card is a kind of greeting) and 'cards' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'place' acts as a link.
Can you help me to learn more?
(Other definitions for on the cards that I've seen before include "Where pips are" , "A merry Christmas is" , "Quite possible (colloq.)" , "Quite likely" , "place for 6 19 [SEASONALMESSAGES]" .)
