How can parents tell if their child’s language development is advanced? A first step is to look at typical language developmental milestones. In other words, it’s key to understand how many words a child is expected to say at various ages, such as at 12 months, 16 months, 18 months, and older. A second step is to look at what advanced speech is. Learn more about gifted children and language development.

Language Development Milestones

Here is what to expect at different ages from infancy until school age in a typically developing child (one who is not advanced or delayed in language development).

First Year

3 months: Makes cooing and gurgling sounds 6 months: Babbles and makes sing-song sounds 12 months: Babbles with inflection, which sounds like talking; says first word 16 months: Says two to five words or more

At 18 Months

Says eight to 10 words others can understandHas a vocabulary of about five to 40 words, mostly nounsRepeats words heard in conversationUses “hi,” “bye,” and “please” when reminded

At 2 Years

Has a vocabulary of 150 to 300 wordsUses two- to three-word sentences, usually in noun-verb combinations, such as “Dog bark,” but also using inflection with combinations like “More cookie?“Refers to self by name and uses “me” and “mine”

At 3 Years

Uses three- to five-word sentencesAsks short questions, usually using “what” or “where"Has a vocabulary of about 900 to 1000 words

At 4 Years

Has a vocabulary of about 1,500 to 2,500 wordsUses sentences of five or more words

At 5 Years

Identifies some letters of the alphabetUses six words in a sentenceUses “and,” “but,” and “then” to make longer sentences

By age 6, a child’s language begins to sound like adult speech, including the use of complex sentences, with words like “when,” for example. However, children tend not to use sentences with “although” and “even though” until about age 10.

Early Language Development

Gifted children tend to begin talking early. While most children say their first word at around 1 year of age, gifted children may begin speaking when they are 9 months old. Some parents report that their children said their first word even earlier than that, as early as 6 months of age. Some parents have even reported that their children tried very hard to form words at 3 months. However, most babies physically can’t control their mouths, tongue, and lips well enough to make speech sounds. They may become quite frustrated by this. Teaching babies sign language is a good way to help them express themselves without vocalization. It’s important to note that not all gifted children speak early. In fact, some gifted children are late talkers, not talking until they are 2 years old or even older. When they do speak, however, they sometimes skip over the typical stages of language development and may begin speaking in full sentences.

Advanced Vocabulary

An advanced vocabulary can mean two different things. It can refer to the number of words a child uses, or it can describe the types of words a child uses. While a non-gifted child may have a vocabulary of 150 to 300 words at age 2, gifted children may have surpassed the 100-word mark by the time they are 18 months old. At 18 months, most children have a vocabulary of from 5 to 20 words, although some do reach the 50-word milestone by the time they are 2 years old. In their second year, most children increase their vocabulary to up to 300 words. Gifted children, however, will have a larger working vocabulary, approaching that of a 4-year-old or even older children. Typically, the first words a child learns will be nouns: mama, daddy, dog, ball, bird, etc. After that, simple verbs are added, for example, want, go, see, give. Gifted children, however, will be adding connecting words, such as and or even because. By age 3, gifted children might also have added transitional words, such as however, or multisyllabic words like appropriate.

Advanced Sentence Structures

A typical 2-year-old can construct sentences of two or three words, often without a verb. For example, a child might say, “There cat” for “There is a cat.” Gifted children, however, will often be able to speak in fuller sentences at age 2. By age 3, a gifted child’s language may already resemble adult speech. They are able to use time markers, like now, later, first, and then, which—along with their advanced vocabulary and more complete sentences—allow them to carry on full conversations with adults.

A Word From Verywell

Although most gifted children have this kind of advanced language development, its absence does not mean a child is not gifted. The range of normal language development is also as widely variable in gifted children as it is in the non-gifted population. These descriptions of what might be typical of a gifted child are meant to help parents understand what advanced language ability looks like.
