Term is used out of respect (6)
I believe the answer is:
mister
'of respect' is the definition.
The definition suggests a singular noun which matches the answer.
'term is used' is the wordplay.
'used' indicates an anagram.
'term'+'is'='termis'
'termis' anagrammed gives 'MISTER'.
'out' acts as a link.
Can you help me to learn more?
(Other definitions for mister that I've seen before include "Form of address to a man, used without his name" , "Merits of form of address to man" , "Male form of address" , "Mr" , "Bloke" .)
