Lucy can say a couple words close to standard English and use them to mean almost what they really mean. They are:

Bye bye (sometimes used correctly but often used as "open this door please")

Uh-oh (I dropped / am planning on dropping something)

She has a few more that are close:

Papa (usually sounds more like bah bah but it means me)

Hee (key)

Dough (Dog, usually Ella)

Beebo (Belly button. Sometimes the pronunciation is better, closer to "bellbuh". But it means belly button, which she's obsessed with, hers mostly but she's intereted in yours too)
