Language development in children is not simply an accumulation of words, but a true transformation of thought. From their very first days, children embark on an invisible journey where their interactions with the world gradually shape their ability to express themselves. This journey, which transforms a simple cry into structured speech, relies on the delicate balance of several fundamental pillars.

It is within this synergy that children find the keys to decode their environment and ultimately make the world their own through the power of language

MAIN STAGES OF LANGUAGE DEVELOPMENT:

- EARLY FORMS OF COMMUNICATION (0 TO 12 MONTHS)

Even before the appearance of the first words, infants are active communicators in what is known as the pre-linguistic stage.

• MEANS OF INTERACTION: From birth, they use crying, sustained eye contact, facial expressions, and body movements to signal their needs.
• VOCALIZATIONS (COOING): Around 2–3 months, the child produces sounds mainly composed of vowels (“ahhh,” “ohhh”). This is a phase of exploring the vocal apparatus and discovering the pleasure of producing sounds.
• COMMUNICATIVE INTENTIONALITY: Around 8–10 months, the child understands that their gestures have an impact. They use pointing to draw an adult’s attention to an object of interest, marking the beginning of conscious social communication.

PHONOLOGY: THE ACQUISITION OF SOUNDS

Phonology refers to the ability to perceive and reproduce the specific sounds of a language.

• LINGUISTIC SPECIALIZATION (6 TO 12 MONTHS): Initially capable of distinguishing all human sounds, the baby begins to focus exclusively on the phonemes of their native language.
• BABBLING (6 TO 9 MONTHS): Characterized by the repetition of syllables (“ba-ba,” “da-da”), babbling helps exercise the articulatory muscles and familiarize the child with the rhythm and intonation of language.
• PROGRESSIVE ACQUISITION: Mastery of sounds follows a biological order: first vowels, then plosive consonants (p, b, t, d), followed by fricatives (f, s, sh), and finally more complex sounds such as “l” and “r.”

LEXICON: VOCABULARY ACQUISITION

The lexicon represents all the words a child understands (receptive vocabulary) and produces (expressive vocabulary).

• FIRST WORDS (AROUND 12 MONTHS): These usually refer to significant people, familiar objects, or basic actions.
• VOCABULARY SPURT (16 TO 18 MONTHS): This is a stage where learning accelerates dramatically. The child realizes that everything in their environment has a name. Their vocabulary can grow from a few dozen to several hundred words in just a few months.

SYNTAX: BUILDING SENTENCES

Syntax is the structure that organizes words to convey complex messages.

• HOLOPHRASE (12 TO 18 MONTHS): The child uses a single word to express a complete idea. For example, “Milk” may mean “I want to drink milk.” Context is essential for adult interpretation.
• TELEGRAPHIC SPEECH (24 TO 30 MONTHS): The first combinations of two or three words appear (“Mommy come,” “More cookie”). The child gradually begins to include grammatical words (pronouns, determiners, prepositions).

LANGUAGE DEVELOPMENT BETWEEN 3 AND 4 YEARS

At this age, skills become significantly more sophisticated. The child gains access to abstract thinking:

• TEMPORAL AND SPATIAL CONCEPTS: They begin to understand and use concepts such as “tomorrow,” “after,” or “behind.”
• VERBAL COMPLEXITY: They produce sentences of four words or more and enter the “Why?” phase, seeking to understand cause-and-effect relationships.
• NARRATION: They can maintain short conversations and recount past or future events, even if some errors in conjugation or pronunciation (such as “sh” or “j” sounds) persist.
