Plod; safari (4)
I believe the answer is:
trip
I believe this is a double definition.
'plod' is the first definition.
(thesaurus)
'safari' is the second definition.
(thesaurus)
(Other definitions for trip that I've seen before include "Catch one's foot" , "Pleasure excursion" , "Journey - miss one's footing" , "Stumble - excursion" , "Journey for some purpose" .)
