Note!
in
dem is converted
into im
Ich bin im Garten
and not:
Ich bin in
dem
Garten
To this rule there is an exception. If you
want to specify the object with a relative
clause, then you have to use in
dem.
Ich bin in
dem Garten,
der dir so gefällt. = I am in
the garden,
that you like so much.
Note!
With verbs of movement in
requires the Accusative , in all other cases
the Dative. In other words, if the translation
into English is to
or into,
then Accusative is to be used, else Dative.
