No idea where you are? Behold the way! (4)
I believe the answer is:
lost
'no idea where you are?' is the definition.
I can't tell whether this definition defines the answer.
'behold the way' is the wordplay.
'behold' becomes 'lo' ('lo' is an archaic exclamation meaning 'look!').
'the way' becomes 'st' (abbreviation for street).
'lo'+'st'='LOST'
Can you help me to learn more?
(Other definitions for lost that I've seen before include "TV series!" , "Not having known where one is" , "Mislaid or irretrievable" , "Suffered defeat" , "Unable to find the way forward" .)
