Maid with rag smeared picture (7)
I believe the answer is:
diagram
'picture' is the definition.
(I've seen this before)
'maid with rag smeared' is the wordplay.
'with' says to put letters next to each other.
'smeared' is an anagram indicator.
'maid' after 'rag' is 'ragmaid'.
'ragmaid' anagrammed gives 'DIAGRAM'.
(Other definitions for diagram that I've seen before include "Chart" , "Simple schematic" , "Outline drawing showing parts or workings" , "picture" , "Simplified drawing" .)
