Questions & Answers about W środę mam spotkanie.
Why is the word for Wednesday środę instead of the dictionary form środa?
When we say "on a day of the week" in Polish, we use the preposition w followed by the Accusative case. For feminine nouns ending in -a like środa, the ending changes to -ę. So, w środę means "on Wednesday".
I thought w meant "in". Why does it translate to "on" here?
You are right that w usually translates to "in" (like being inside a building). However, prepositions rarely match up perfectly between languages. In Polish, the set rule for days of the week is to use w to mean "on".
Why is there no word for "I" before mam?
The verb mam already means "I have". In Polish, you usually drop subject pronouns like ja (I) because the verb's ending tells us who is doing the action. Adding ja here would sound unnatural unless you wanted to heavily emphasize that I have a meeting, as opposed to someone else.
The verb mam requires an object in the Accusative case. Why doesn't the ending of spotkanie change?
You are correct that mieć (to have) takes the Accusative case. However, spotkanie (meeting) is a neuter noun because it ends in -e. A handy rule in Polish is that neuter nouns always look exactly the same in the Accusative case as they do in their basic dictionary form.
