Is this normal for a newly talking 2 year old?

Sounds as though she is just learning to pronounce the words (which may not be anything to worry about yet- at 18 months my son only said mama, dada, and baba- his word for bottle, even after he only used a sippy cup and he speaks perfectly well now). She just needs practice in when to use them correctly. Trial and error is the only real way to learn a language. My advice is, don't correct her... but use the correct speech when asking her back. For example, when she says "more" for when she's hungry, don't tell her, "No, we say, I'm hungry." Just ask her, "Are you hungry? Do you want to eat? Come on, let's eat." And give her some food. She'll begin to ociate those words with what she wants as well. When she's finished, ask her if she wants more. She'll catch on. Good luck. :)
