Copying material for exercise equipment (5)
I believe the answer is:
toner
'equipment' is the definition.
Both the answer and definition are singular nouns.
Perhaps they are linked in a way I don't understand?
'copying material for exercise' is the wordplay.
'copying material' becomes 'r' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'for' means one lot of letters go next to another (I've seen this in other clues).
'exercise' becomes 'tone' (toning is a kind of exercising).
'r' after 'tone' is 'TONER'.
Can you help me to learn more?
(Other definitions for toner that I've seen before include "Material for printer" , "Skin-cleansing lotion" , "Black or coloured powder used in a printer" , "Lotion for cleansing the skin" , "Chemical solution used to soften colours" .)
