Black stuff with light brown pattern from Scotland (6)
I believe the answer is:
tartan
'pattern from scotland' is the definition.
'tartan' can be an answer for 'pattern' (I have seen 'Pattern of clan' mean 'tartan' so perhaps 'pattern' could also mean 'tartan'). I'm not sure about the 'from scotland' bit.
'black stuff with light brown' is the wordplay.
'black stuff' becomes 'tar' (tar is a black substance).
'with' says to put letters next to each other.
'light brown' becomes 'tan' (tan is a light brown colour).
'tar'+'tan'='TARTAN'
Can you help me to learn more?
(Other definitions for tartan that I've seen before include "dress?" , "Criss-cross pattern" , "Symbol of the Scottish clans." , "Scottish check" , "Scots material" .)
