Writing paper and a pill (6)
I believe the answer is:
tablet
This clue might be a double definition.
'writing paper' is the first definition.
'tablet' can be an answer for 'paper' (tablet is a kind of paper). I'm not certain of the 'writing' bit.
'a pill' is the second definition.
('tablet' can be a synonym of 'pill')
'and' is the link.
Can you help me to learn more?
(Other definitions for tablet that I've seen before include "Small bar of soap" , "A small pill or an inscribed panel on wall" , "Pill; writing pad" , "Medicine - flat slab - computer" , "Handheld personal computer" .)
