I'm sorry but I couldn't understand the question fully. :/
var : 'in existance' or 'in presence' (there is) or expresses possession (to have).
Dünya var : 'The world exists.'
Para var : 'There is money.'
Param var: 'I have money.'
When you use this construction: 'para' + possessive suffix '-m', 'param' (my money) you are literally saying 'my money exists' and this is how we say 'i have' in Turkish.
Arabam var: 'I have a car.'
'mı' is a question particle which can turn almost anything into a question:
var mı : does it exist?, is there?, do i have?, ...
There's no such thing as varmım.
