The Polish preposition z followed by the instrumental case is translated as with.
Male and neuter singular nouns end with em and feminine nouns end with ą in the instrumental. This rule is sufficient to recognise most instrumental singular endings.
Some examples of the instrumental using example sentences:
| Mieszkam w domu z ogrodem | I live in a house with a garden |
| Lubię spędzać czas z rodziną | I like to spend time with family |
| Lubię spędzać czas z przyjaciółmi | I like to spend time with friends |
