Cross lively people in vacated terrace (8)

I believe the answer is:
traverse
'cross' is the definition.
(synonyms)
'lively people in vacated terrace' is the wordplay.
'lively people' becomes 'ravers' (raver is a kind of person. I am not sure about the 'lively' bit.).
'in' means one lot of letters goes inside another.
'vacated' says to hollow out the word (remove centre letters) (internal letters vacate the word).
'terrace' with its middle removed is 'te'.
'ravers' going within 'te' is 'TRAVERSE'.
Can you help me to learn more?
(Other definitions for traverse that I've seen before include "Ski diagonally across (a slope)" , "get across" , "Extend or bridge across" , "Move across" , "In mountaineering, a steep slope to be crossed from side to side" .)
