Better? Spring inside and splash with dirty water? (9)
I believe the answer is:
bespatter
'splash with dirty water?' is the definition.
'bespatter' can be an answer for 'splash' (I've seen this in another clue). I am not certain of the 'with dirty water?' bit.
'better? spring inside' is the wordplay.
'spring' becomes 'spa' (spa can mean a mineral spring).
'inside' means one lot of letters goes inside another.
'better' going around 'spa' is 'BESPATTER'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for bespatter that I've seen before include "Dirty" , "Spray with droplets" , "Defame" , "Make mess of" .)
