Secures Greek fruit (8)
I believe the answer is:
grapples
'secures' is the definition.
The answer and definition can be both to do with contact as well as being verbs in their -s form.
Perhaps there's a link between them I don't understand?
'greek fruit' is the wordplay.
'greek' becomes 'gr' (abbreviation for Greek).
'fruit' becomes 'apples' (apple is a type of fruit).
'gr'+'apples'='GRAPPLES'
Can you help me to learn more?
(Other definitions for grapples that I've seen before include "Wrestles or struggles at close quarters" , "deals" .)
