Upwards of 101 meeting points (4)
I believe the answer is:
foci
'points' is the definition.
(focus is a kind of point)
'upwards of 101 meeting' is the wordplay.
'upwards' shows that the letters should be reversed in order.
'101' becomes 'ci' (roman numerals).
'meeting' means one lot of letters go next to another.
'of' in reverse letter order is 'fo'.
'fo'+'ci'='FOCI'
(Other definitions for foci that I've seen before include "Points for attention" , "Central points (of the greatest activity)" , "fixed points" , "targets" , "Centres" .)
