Lacking assurance about getting home safe (8)

Ross

I believe the answer is:

insecure

I'm a little stuck... Click here to teach me more about this clue!

'lacking assurance about' is the definition.
I can't tell whether this definition defines the answer.

'home safe' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'safe' becomes 'secure' (similar in meaning).
'in'+'secure'='INSECURE'

'getting' acts as a link.

Can you help me to learn more?

(Other definitions for insecure that I've seen before include "uncertain" , "Fearful, unsafe." , "Sinecure for those lacking in confidence" , "Not safe or confident in oneself" , "Timid" .)
