Faulty elements limiting the Dualit range (8)
I believe the answer is:
latitude
'range' is the definition.
(I know that latitude is a type of range)
'faulty elements limiting the dualit' is the wordplay.
I cannot really understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
an anagram of 'dualit' is 'laitud' which is present in the remaining letters.
A single letter 'e' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for latitude that I've seen before include "Imaginary lines around the earth" , "Poles' approach increases such" , "Imaginery line around the earth" , "non-existent at the Equator?" , "Freedom from restriction" .)
