Telegraphic Speech and the Vocabulary Spurt
Captions available
The idea
Telegraphic speech, two-word phrases such as "more cookie," appears at eighteen to twenty-four months, alongside a vocabulary spurt from about fifty to two hundred words by two.
In practice
Up to a thousand words by three, many learned by fast mapping after a single hearing.
Where people slip
Receptive vocabulary runs ahead of productive: infants recognise common nouns by about six months.
