The language is so diversed that dialects play a big role here. I will only include the standard Bahasa Indonesia, but your way of speaking will be so formal. Instead of words, i'll give you sentences with meanings. 1.

Saya / mau / makan. I / want to / eat. Simple, right? 2. Andre / sedang main / bola. Andre / is playing / the ball. Bahasa Indonesia don't have definite article, but we have indefinite articles (this is what my teacher taught me). You may also look into suffixes and prefixes as they play a pretty big role in proper Bahasa Indonesia (when talking between friends, most people use improper dialects) 3. Siska / bernyanyi. Siska / sings. 4. Topan / mencari / anjingnya / yang / hilang / kemarin. Topan / is searching for / his dog / that / have been lost / yesterday. the suffix -nya is used in anjingnya as a way to show possesion 5. Bambang / membunyikan / lonceng sekolah. Bambang / rings / the school bell.

I think that's enough for a headstart as I rarely used proper Bahasa Indonesia.
