With which to write three Roman numerals? (6)
I believe the answer is:
pencil
'write three roman numerals?' is the definition.
'pencil' can be an answer for 'write' (thesaurus). I am not sure about the 'three roman numerals?' bit.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for pencil that I've seen before include "Drawing instrument" , "Wooden writer" , "Drawer with graphite in" , "Implement for writing, drawing etc" , "Writing implement with graphite centre" .)
