Need polishing up on anagrams? Try us! (5)
I believe the answer is:
rusty
'need polishing up' is the definition.
I can't tell whether this definition defines the answer.
'anagrams? try us' is the wordplay.
'anagrams?' indicates an anagram (I've seen 'anagram' mean this).
'try'+'us'='tryus'
'tryus' anagrammed gives 'RUSTY'.
'on' is the link.
Can you help me to learn more?
(Other definitions for rusty that I've seen before include "Affected by corrosion - out of practice" , "Stiff with age" , "(Of iron) corroded" , "Oxidised, corroded" , "Reddish," .)
