Straight mole from Homeland (4)
I believe the answer is:
hand
'straight' is the definition.
(thesaurus)
'mole from homeland' is the wordplay.
'from' suggests deleting specific letters.
'homeland' with 'mole' removed is 'HAND'.
(Other definitions for hand that I've seen before include "Fingered organ" , "employee" , "Clock-pointer" , "Unit of measurement of a horse's height" , "Help < and applause" .)
