Put writing material back in press that's tight (5-4)
I believe the answer is:
close-knit
'tight' is the definition.
(I've seen this in another clue)
'put writing material back in press' is the wordplay.
'put' indicates putting letters inside.
'writing material' becomes 'ink' (substance for writing with).
'back' is a reversal indicator.
'in press' becomes 'closet' (synonyms. I am not sure about the 'in' bit.).
'ink' written backwards gives 'kni'.
'kni' inserted inside 'closet' is 'CLOSE-KNIT'.
'that's' is the link.
Can you help me to learn more?
(Other definitions for close-knit that I've seen before include "United or joined together - with wool?" , "Bound together by strong relationships" , "Bound by strong ties" , "Intimate as a group" , "Tightly bound together" .)
