Is one sign in nice restoration sharp and to the point? (8)
I believe the answer is:
incisive
'sharp and to the point?' is the definition.
I can't tell whether this defines the answer.
'is one sign in nice restoration' is the wordplay.
'one sign' becomes 'iv' (I can't explain this - if you can you should give a lot more credence to this answer).
'in' indicates putting letters inside.
'restoration' is an anagram indicator (I've seen this in other clues).
'is'+'iv'='isiv'
'nice' is an anagram of 'ince'.
'isiv' inserted within 'ince' is 'INCISIVE'.
Can you help me to learn more?
(Other definitions for incisive that I've seen before include "Piercing" , "(Of action) quick, direct" , "Clear and probing, trenchant" , "Clear and penetrating, as of speech" , "Intelligently analytical and clear-thinking" .)
