Nothing original, indeed, in restricting direction (3-3)
I believe the answer is:
one-way
'nothing original indeed in restricting direction' is the definition.
I can't judge whether this definition defines the answer.
'nothing original indeed' is the wordplay.
'nothing' becomes 'O' (O resembles 0).
'original' becomes 'new' (similar in meaning).
'indeed' becomes 'ay' ('ay' and 'aye' can mean yes).
'o'+'new'+'ay'='ONE-WAY'
Can you help me to learn more?
(Other definitions for one-way that I've seen before include "This street allows only single traffic flow" , "Unidirectional" , "Single-directional like some streets" , "Kind of street where cars shouldn't meet head-on" , "Moving in a single direction only" .)
