if
 

how would you express if in a sentence like.

if i was hungry i would eat that.

Well, one way is to use the -tara form (mind you, I haven't had a lot of practice with this!)

If I'm not mistaken, I believe your example sentence would sound like:

"Onaka ga suitara sore o tabemasu."

But that may be more like "If I'm hungry, I'll eat that"

...I tried ^_^;;

Oo. Thank you!
