Ask for worshipper in speech? (4)
I believe the answer is:
seek
'ask for' is the definition.
(I've seen this in another clue)
'worshipper in speech?' is the wordplay.
'worshipper' becomes 'Sikh' (believer in Sikhism).
'in speech?' shows a homophone (sound like) (I've seen 'in speech' mean this).
'sikh' sounds like 'SEEK'.
(Other definitions for seek that I've seen before include "Ask for (permission)" , "Try to find" , "Go looking for" , "Attempt - search" , "'. . . . and ye shall find'" .)
