Drab ironing captivates writer (4)
I believe the answer is:
biro
'writer' is the definition.
(type of pen, something which writes)
'drab ironing captivates' is the wordplay.
'BIRO' is hidden within the letters.
However, I am uncertain how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for biro that I've seen before include "Lazlo -, ballpoint pen inventor" , "writer" , "Laszlo Jozsef -, ballpoint pen inventor" , "Pocket item" , "Writing implement" .)
