Travelling a lot is origin of extended quarantine (7)

Ross

I believe the answer is:

isolate

'quarantine' is the definition.
(I've seen this before)

'travelling a lot is origin of extended' is the wordplay.
'travelling' indicates an anagram.
'origin of' suggests taking the first letters.
The initial letter of 'extended' is 'e'.
'a'+'lot'+'is'='alotis'
'alotis' is an anagram of 'isolat'.
'isolat'+'e'='ISOLATE'

(Other definitions for isolate that I've seen before include "Single out" , "Place in seclusion" , "Cut off; quarantine" , "Put into quarantine" , "Point out" .)

I've seen this clue in The Telegraph.
