Nervous individual going to Germany, for instance getting a lift (2,4)
I believe the answer is:
on edge
'nervous' is the definition.
(on edge can mean nervous or tense)
'individual going to germany for instance getting a lift' is the wordplay.
'individual' becomes 'one' (an individual is one person).
'going to' is a charade indicator (letters next to each other).
'germany' becomes 'd' (vehicle registration code for Deutschland).
'for instance' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'getting a lift' says the letters should be written in reverse (in a down clue, letters go up).
'eg' reversed gives 'ge'.
'one'+'d'+'ge'='ON EDGE'
(Other definitions for on edge that I've seen before include "Tense and irritable, very nervous" , "Twitchy" , "Nervy, tense and irritable" , "Fidgety, nervous" , "close to border" .)
