Brand added alongside potter's material (8)
I believe the answer is:
claymore
'brand' is the definition.
Both the answer and definition are singular nouns.
Perhaps they are linked in a way I don't understand?
'added alongside potter's material' is the wordplay.
'added' becomes 'more' (similar in meaning).
'alongside' means one lot of letters go next to another.
'potter's material' becomes 'clay' (I've seen this in another clue).
'more' after 'clay' is 'CLAYMORE'.
Can you help me to learn more?
(Other definitions for claymore that I've seen before include "Highland sword" , "mine, sort of" , "Two-edged broadsword" , "Scottish sword wielded by my oracle" , "Scottish highlander's sword" .)
