From 12–24 months, babies can recognize the correct pronunciation of familiar words. Babies also use phonological strategies to simplify word pronunciation. Some strategies include repeating the first consonant-vowel in a multisyllable word ('TV' → 'didi') or deleting unstressed syllables in a multisyllable word ('banana' → 'nana'). Within this first year, two word utterances and two syllable words emerge. This period is often called the holophrastic stage of development, because one word conveys as much meaning as an entire phrase. For instance, the simple word "milk" can imply that the child is requesting milk, noting spilled milk, sees a cat drinking milk, etc. One study found that children at this age were capable of comprehending 2-word sentences, producing 2–3 word sentences, and naming basic colors.
