The other word she has been saying is "daddy." A few days ago she pointed to me and very clearly said "da-ee." Then she pointed to me in our wedding photo and repeated it.
I was of course totally blown away by this! But since then there has been some evidence that she has a more expansive definition of the word than others do. A variety of other things sometimes get called "da-ee" as well (e.g. Mama, the doorframe, a candle, random other pictures, etc.).
There are other words on the cusp too, like "mama" and "baby." This is just another reminder that there is no bright line between speaking and non-speaking and that we evolve into it gradually. But there is no doubt that Quinn absolutely wants to communicate and will probably be talking up a storm before we know it.
