Messy handwriting (6)
I believe the answer is:
scrawl
'messy handwriting' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for scrawl that I've seen before include "Quickly pen" , "Write poorly, bad handwriting" , "Illegible handwriting" , "Crawls away from bad writing" , "write hurriedly" .)
