Explanation:
It depends on the manner you say it :)
but yeah. btw, no one say "dar" in spanish for parties.
we say, "I'm gonna make"
They end that way because they are in "infinitivo", infinitive. It is the equivalent of saying "to x"
Eg.
Aprender - to learn
Vivir - to live
Encontrar - to find
The conjugation (-er, -ir or -ar) depends on each word, it is a matter of memorising them, I'm afraid.
Hope this helped :)
