Frogman has time to switch (6)
I believe the answer is:
divert
'to switch' is the definition.
(thesaurus)
'frogman has time' is the wordplay.
'frogman' becomes 'diver' (synonyms).
'has' says to put letters next to each other.
'time' becomes 't' (abbreviation).
'diver'+'t'='DIVERT'
(Other definitions for divert that I've seen before include "Turn from normal course, say traffic" , "Amuse or send another way" , "Distract" , "Entertain; reroute" , "Entertain or turn from course" .)
