Noticed a sharp object (3)
I believe the answer is:
saw
'noticed' is the definition.
'a sharp object' is the wordplay.
'a sharp' becomes 'sa' (I can't justify this - if you can you should believe this answer much more).
'object' becomes 'w' (W is an example).
'sa'+'w'='SAW'
Can you help me to learn more?
(Other definitions for saw that I've seen before include "Perceived visually" , "item in tool kit" , "Cutting tool - did 23" , "Carpentry tool" , "Hand tool; proverb" .)
