Gadgets displaying pretension (3,7)
I believe the answer is:
tin openers
'gadgets' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'displaying pretension' is the wordplay.
'displaying' indicates an anagram (the anagrammed letters display the answer).
'pretension' is an anagram of 'TIN-OPENERS'.
Can you help me to learn more?
(Other definitions for tin openers that I've seen before include "Kitchen utensils" , "kitchen equipment" .)
