Beginning of sale — writing material to fall in price? (4)
I believe the answer is:
sink
'fall in price?' is the definition.
'sink' can be an answer for 'fall' (I've seen this in another clue). I'm not certain of the 'in price?' bit.
'beginning of sale writing material' is the wordplay.
'beginning of' says to take the initial letters.
'writing material' becomes 'ink' (substance for writing with).
The initial letter of 'sale' is 's'.
's'+'ink'='SINK'
'to' is the link.
Can you help me to learn more?
(Other definitions for sink that I've seen before include "drink" , "Plumbing fixture" , "Drop in the ocean?" , "place of corruption" , "Succeed in putting" .)
