Pal drops in at random after lunch (12)

Ross

I believe the answer is:

postprandial

'after lunch' is the definition.
(postprandial means after a meal)

'pal drops in at random' is the wordplay.
'random' indicates anagramming the letters.
'pal'+'drops'+'in'+'at'='paldropsinat'
'paldropsinat' anagrammed gives 'POSTPRANDIAL'.

(Other definitions for postprandial that I've seen before include "type of speech?" , "After dinner" , "Immediately after a meal" , "Wet blanket" , "after eating" .)

I've seen this clue in The Guardian.
