Points in short typeface set up ready for use (6)
I believe the answer is:
instal
'ready for use' is the definition.
(to instal is to ready something for use)
'points in short typeface set up' is the wordplay.
'points' becomes 'sn' ().
'in' means one lot of letters goes inside another.
'short' means to remove the last letter.
'typeface' becomes 'latin' (as in a Latin typeface).
'set up' says the letters should be written backwards.
'latin' with its final letter taken away is 'lati'.
'sn' put inside 'lati' is 'latsni'.
'latsni' written backwards gives 'INSTAL'.
(Other definitions for instal that I've seen before include "institute" , "Invest in office" , "Put in position" , "Put in place and make ready for use" , "Place equipment in position" .)
