Was the first time and one took a good look round it (7)
I believe the answer is:
'was the' is the definition.
I can't judge whether this defines the answer.
'first time and one took a good look round it' is the wordplay.
I cannot quite see how this works, but
'first' could be 'start' (synonyms) and 'start' is found within the answer.
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is located in the answer.
A single letter 'd' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for started that I've seen before include "Originated" , "Began; flinched" , "Made sudden movement from pain or surprise" , "showed surprise" , "kicked-off" .)
