In which extremities are measured? (4)
I believe the answer is:
feet
'measured?' is the definition.
The definition and answer are not the same part of speech.
'in which extremities are' is the wordplay.
'in which' becomes 'fe' (I can't explain this - if you can you should believe this answer much more).
'extremities' means to remove the middle letters (I've seen 'extremities of' mean this).
'are' becomes 'exist' ('they are' means 'they exist').
'exist' with its centre removed is 'et'.
'fe'+'et'='FEET'
Can you help me to learn more?
(Other definitions for feet that I've seen before include "Unit used to measure" , "Three of these in yard" , "On which we stand" , "Measures - body parts" , "Have both on the ground to be practical" .)
