Prepositions are words or phrases that are typically placed before the substantive and showing a relation of the substantive to an adjective or a verb. Prepositions come in very handy to show a relation between two completely different objects. Take for example:
The ball is on the table : The preposition ‘on’ shows the relation between the ball and the table.
The nine prepositions, mainly, are placed in the order :
di - of
a – to/at
da - from
in – in
con - with
su - on
