Telegraphic speech

Telegraphic speech, according to linguistics and psychology, is speech during the two-word stage of language acquisition in children, which is laconic and efficient.

The name derives from the fact that someone sending a telegram was generally charged by the word. To save money, people typically wrote their telegrams in a very compressed style, without conjunctions or articles. As children develop language, they speak similarly: when a child says "Daddy here", it is understood that the child means "Daddy is here", omitting the copula. The words dropped in this style of speech are closed class or functional words.
