Wash up for a pal (3)
I believe the answer is:
lap
'wash' is the definition.
(thesaurus)
'up for a pal' is the wordplay.
'pal' anagrams to 'LAP'.
However, I am unsure how this is indicated.
Can you help me to learn more?
(Other definitions for lap that I've seen before include "400 metres, typically" , "Scoop up with the tongue" , "Round in a race" , "Stage - circuit" , "One round of the course" .)
