Tin or tape cutter (6)
I believe the answer is:
opener
This might be a double definition.
'tin' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'tape cutter' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'or' acts as a link.
Can you help me to learn more?
(Other definitions for opener that I've seen before include "First act" , "Tins need one" , "cricketer, first at the crease?" , "Batsman who starts innings" , "First event in a series" .)
