Throws away out-of-date jams? (4)
I believe the answer is:
bins
'throws away' is the definition.
The definition and answer can be both to do with contact as well as being verbs in their -s form.
Maybe there's a link between them I don't understand?
'out-of-date jams?' is the wordplay.
'out of' suggests deleting specific letters.
'date' becomes 'd' (abbreviation e.g. dob - date of birth).
'jams?' becomes 'binds' (I've seen this in another clue).
'binds' with 'd' removed is 'BINS'.
Can you help me to learn more?
(Other definitions for bins that I've seen before include "aid to viewing" , "Rejects" , "Containers for refuse" , "Rubbish receptacles" , "Containers for wine or rubbish" .)
