PREPOSITIONS
Whilst you will need to learn the vocabulary for some prepositions, you will also need to know what case they take as well! Every preposition in Latin is followed by a noun in a certain case. I have grouped the prepositions in terms of which case they take after.
Accusative Case:
ad + accusative = to, towards
circum + accusative = around
contra + accusative = against
in + accusative = into, onto (in can also be added to the beginning of verbs to show motion towards)
inter + accusative = among, between
per + accusative = through, along
prope + accusative = near
propter + accusative = on account of, because of
sub + accusative = under, beneath (for movement)
trans + accusative = across (trans can also be added to the beginning of verbs to show motion across)
Ablative Case:
a, ab + ablative = by, from, away from (a/ab can also be added to the beginning of verbs to show motion away from)
cum + ablative = with
de + ablative = from, down from, about
e, ex + ablative = from, out of, out
in + ablative = in, on
pro + ablative = in front of, for, in return for
sine + ablative = without
sub + ablative = under, beneath (for location)
Once you have learnt what case each preposition takes, it is easy to spot their noun!
