Language Development

Language development refers to the range of skills that enable a child to understand and use language to communicate with others. It encompasses oral language (understanding and speaking), as well as skills that gradually support the learning of reading and writing, such as knowledge of letters, phonological awareness and the alphabetic principle. These skills develop gradually through interactions with others, play and everyday experiences.

The stages of language development

6 to 18 months old

The baby gradually begins to understand simple words and instructions.
They first produce sounds and babbling, then pronounce their first words.
Talking with adults, singing songs, telling stories and naming objects around them promote their language development.

18 months to 2½ years old

The child understands increasingly complex instructions and progressively combines multiple words to form short sentences.
Their vocabulary grows rapidly, allowing them to better express their needs, ideas and experiences.
They increasingly enjoy communicating with others during everyday activities.

2½ to 3 years old

The child answers increasingly varied questions and produces more complete sentences.
They begin to describe short situations, gradually make connections between cause and effect, and often show curiosity about why things happen.
Their pronunciation gradually improves, even if some sounds remain difficult.
The child may become interested in letters, especially the letters in their first name.

3 to 3½ years old

The child’s language becomes increasingly elaborate. They begin to express cause and effect relationships. For example, they might say, “I wasn’t happy because Charlotte hit me.” This is often the stage when the famous “Why?” question emerges.
The child gradually improves their pronunciation, even if they still have difficulty producing certain sounds.

3½ to 4 years old

The child gradually understands certain abstract concepts, including those concerning size (“bigger than”), space (“in front of”) and time (“after”).
The child begins to use longer sentences and increasingly includes short words such as “a” and “the.” When they forget them, you can simply rephrase their sentence and emphasize the missing words.

4 to 4½ years old

The child gains a better understanding of spatial, temporal and size concepts. They gradually become more adept at following instructions that involve these concepts.
The child is increasingly able to understand the connections in the stories they are told.
The child gradually develops their ability to deduce information that is not explicitly given in a situation.
The child increasingly uses sentences that include several verbs. They increasingly enjoy describing and talking about events.

4½ to 5 years old

Their growing vocabulary helps them develop increasingly advanced categorization skills.
The child tells stories more coherently and provides more context for the listener.
The child gradually develops their ability to play with syllables and rhymes.
The child also learns to recognize and name an increasing number of letters, then gradually develops their ability to trace them.

5 to 6 years old

The child begins to understand that certain words can have multiple meanings and gradually develops their understanding of figurative language and humour.
They are able to explain the steps of a procedure, tell a story with multiple events and formulate a riddle in an organized way.
They begin to notice the smallest sounds of language (phonemes), discover that these sounds can be represented by letters or groups of letters and gradually make the connections between the sounds they hear and the letters they see.

6 to 8 years old

The child learns to associate letters and groups of letters (e.g. “th,” “sh”) with corresponding sounds in order to read and write words.
The child learns to merge multiple sounds to form a word (e.g., “t” + “r” + “ee” = tree) and to segment a word into its different sounds.
The child increasingly uses their knowledge of sounds and letters to write words and gradually learns spelling rules.
As they recognize words more quickly, the child can devote more attention to understanding what they are reading.

Remember

The ages presented are approximate. Each child develops at their own pace, and different language skills often emerge simultaneously. The development of oral language gradually supports the acquisition of reading and writing skills, while these new skills, in turn, contribute to further enriching the child’s language. It is the child’s overall progress and development that is important, rather than reaching a specific stage at a particular age.
