open

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

'start with' is the definition.
'open' can be an answer for 'start' (opening is a kind of starting). I'm not sure about the 'with' bit.

'parking in the wrong one' is the wordplay.
'parking' becomes 'p' (abbreviation on road signs).
'in' indicates putting letters inside.
'the wrong' indicates an anagram.
'one' is an anagram of 'oen'.
'p' going inside 'oen' is 'OPEN'.

'to' acts as a link.

Can you help me to learn more?
