Struggles, seeing Greek tech company succeeded (8)
I believe the answer is:
grapples
'struggles' is the definition.
(grapple is a kind of struggle)
'greek tech company succeeded' is the wordplay.
'greek' becomes 'gr'.
'tech company' becomes 'apple'.
'succeeded' becomes 's' (genealogical abbreviation).
'gr'+'apple'+'s'='GRAPPLES'
'seeing' is the link.
(Other definitions for grapples that I've seen before include "Wrestles or struggles at close quarters" , "deals" .)
