Multiword utterances

In their earliest multiword utterances, children are inconsistent in their use of function words (grammatical morphemes) such as "a" and "the", subject pronouns like "I" and "we", auxiliary verbs such as "can" and "is", and in some languages, verbal inflection.
Such utterances are cometimes called (telegraphic speech).
The following are some examples:
Can stand up table.
What that?
No sit there.
Ride truck
Snow mommy that.

Cathy build house.
