DD is 20 months, and has (I think) a pretty large vocabulary (conservative guess is about 300 words) - nouns, verbs, adjectives which she uses correctly and in context (discounting the echoing that she does).
But other than the occasional putting together she doesn't yet have any sentences, or they are backwards, so 'necklace...wear'. She once said 'where's sylvia?' (my mother). Anyone else had this with their DCs - I'm not at all worried, just curious as my very limited knowledge of small children suggests that this is slightly unusual. I assume that once she 'gets' it, she'll just talk. She can also get pretty much anything she wants, so has no real reason to hurry. Did anybody else's kid learn like this, or am I just on another planet?
