"If called by a panther, don't anther” writer (4)
I believe the answer is:
nash
(Other definitions for nash that I've seen before include "Marble Arch designer" , "Ogden -, US poet, wit" , "Uncontrollable emotion" , "English architect, d. 1835 - American poet, d. 1971" , "Ogden --, US humorous poet" .)
