Telegraphic Speech.

Explanation:

The Telegraphic Stage of the Language Development occurs at the age of two or two-and-a-half years. The term 'telegraphic' is used in relation to the words that we use in telegraphs, short. The term was fabricated by Roger Brown and Colin Fraser in 1963 in their book titled 'The Acquisition of Syntax.'
