"I wish to drink water."
Translation:Yo deseo beber agua.
Dtucker - quiero in this context would be 'want'. It's also used elsewhere to say 'love' regarding a person. I am not aware of quiereo que as being used for 'wish'. It too can mean 'want' and I believe you would use it when you want to emphasis strongly that you want something. Desear is the verb for wish as presented.
