Note about wild partygoers makes us cross (8)
I believe the answer is:
traverse
'cross' is the definition.
(I know that cross can be written as traverse)
'note about wild partygoers' is the wordplay.
'note' becomes 'te' (musical note as in do re mi fa so la ti).
'about' means one lot of letters goes inside another.
'wild partygoers' becomes 'ravers' (people attending a rave. I am not sure about the 'wild' bit.).
'te' enclosing 'ravers' is 'TRAVERSE'.
'makes us' acts as a link.
Can you help me to learn more?
(Other definitions for traverse that I've seen before include "Cross sideways" , "Travel across or pass over" , "Move across" , "Ski diagonally across (a slope)" , "cover" .)
