Leave hastily from self-catering apartment on vacation (4)
I believe the answer is:
scat
'leave hastily' is the definition.
(I've seen this in another clue)
'self-catering apartment on vacation' is the wordplay.
'self catering' becomes 'sc' (this could be a standard abbreviation I've not previously seen).
'apartment' becomes 'apt' (abbreviation in property ads for example).
'on vacation' suggests removing the centre (after the inside letters have vacated the word).
'apt' with its middle removed is 'at'.
'sc'+'at'='SCAT'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for scat that I've seen before include "Animal droppings - small silvery fish" , "Wordless singing style" , "improvisation in jazz" , "way to sing > "Go away!"" , "Style of jazz singing" .)
