Names for knobs? (7)
I believe the answer is:
handles
I believe this is a double definition.
'names' is the first definition.
(handle can mean a name or nickname)
'knobs?' is the second definition.
(knob is a kind of handle)
'for' is the link.
(Other definitions for handles that I've seen before include "Feels" , "Parts to be grasped" , "Manipulates" , "Deals with" , "Names" .)
