M.K.
It sounds like she's just focusing on talking and intellectual learning right now - she seems to be way ahead of most kids her age in those areas. Try not to worry about the walking too much, she'll probably catch on in the next month or so.
My nephew didn't walk until he was 18 months old, but then we learned to ride a proper two-wheel bike without training wheels before his third birthday - so being a late walker doesn't necessarily have any impact on later motor skills.
