Fancy gadget shown in Bond film's teaser? (3,4)
I believe the answer is:
tie clip
'fancy gadget' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'bond film's teaser?' is the wordplay.
'bond' becomes 'tie' (both can mean a connection).
'film's teaser?' becomes 'clip' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'tie'+'clip'='TIE-CLIP'
'shown in' acts as a link.
Can you help me to learn more?
(Other definitions for tie clip that I've seen before include "Man's ornamental clasp" , "Neckwear securer" , "clothing accessory" .)
