telegraphic speech
At approximately age 2, children enter the Two-Word Stage of language development. During this stage they exhibit telegraphic speech, which is speech that sounds very much like a telegram, has words arranged in an order that makes sense, and contains almost all nouns and verbs. For example, a child at this stage of development who wants to get milk may say "get milk", as opposed to saying just "milk". As you can see, there are only two words, they are in an order that makes sense, there is one verb and one noun, and it sounds like a telegram.
