spills

I'm a little stuck... Click here to teach me more about this clue!

'pours' is the definition.
(spilling is a kind of pouring)

'out small tablets' is the wordplay.
'out small' becomes 's' (abbreviation - e.g. clothes size. I am not sure about the 'out' bit.**).
'tablets' becomes 'pills' ('pill' can be a synonym of 'tablet').
's'+'pills'='SPILLS'

Can you help me to learn more?

(Other definitions for spills that I've seen before include "Pieces of rolled paper used to light fires" , "Pieces of rolled paper used to light a fire" , "Causes liquid to flow out" .)
