Children between the ages of 18 and 30 months begin to speak in a telegraphic manner. They use sentences that are usually comprised of two words (until the age of 24; more words from that age on) that are essential for the meaning of the message being conveyed. Nouns and verbs are the ones commonly used, while adjectives and prepositions, for instance, are left out. An example of telegraphic speech is, "Dog drink milk."
