The child as an individual has particular capacities, has rights, and navigates the speech and language pathway by his or her own schedule. This bears on whether a child needs speech and language therapy, and if a child does, when this should be.

Irregularities
Universals and Universal Grammar
Hidden by the way language evolved
Infinite creativity
In two senses, in the sense of poetry and in the sense of ‘discrete infinity'
