At 1 year,sentences begin with the one-word holophrase,in which one word represents a complete thought (e.g. ,"out" for "I want to go out.").A 2-year-old uses simple two-word phrases- "all gone," "me up,""baby crying." This is called telegraphic speech,which is usually a combination of a noun and a verb and includes only words that have concrete meaning.
