Lesson 2: Language Acquisition from 1.5 to 6 Years Old

In this lesson, we continue from what you learned in the previous lesson and take a closer look at the three stages of acquiring language after 18 months old.

Key Concepts

  • Two-Word Stage 

  • Telegraphic Stage

  • Multi-Word Stage

  • Syntax (Phrases and Sentences)

  • Morphology (Structure of Words)

  • Over-regulation

Unit 1: Two-Word Stage and Telegraphic Stage

The two-word stage usually starts around having achieved the 50-word milestone. This stage generally occurs from 18 to 24 months and signifies the transition from single words to more complex linguistic structures. Children start to combine two words to create 'mini-sentences’ with simple semantic (relating to meaning in language) correlations.

Children follow the word order rules of the target language from early on. In English, the word order is as follows: Subject – Verb – Object (SVO). So, even though children in the two-word stage do not yet talk in complete sentences, you would not hear the following utterance from a 20-month-old: 'cookie want'. As the SVO order is already engraved in its linguistic repertoire – thanks to the Language Acquisition Device (LAD) – the young child would rather say 'want cookie' to express their desire.

In the two-word phase, the child’s 'mini-sentences' usually consist of two content words – words that have meaning and are primarily nouns and verbs. However, morphological and syntactic features are still lacking. For that reason, contextual cues such as non-verbal communication (gaze, pointing, facial expression) and familiarity with the child are important to understand the exact meaning of the utterance. That is also why strangers usually struggle to understand young children.

Two-word stage: 

What could these different ‘two-word expressions’ mean? How do we know what the child is saying?

Utterances:

  1. 'Cat play'

  2. 'No veggie'

  3. 'Mommy car'

​

Telegraphic stage:

In 1958, Jean Berko Gleason created the Wug Test, which you can see in the picture on the left.

Unit 2: Multi-Word Stage

Alongside having an evermore increasing vocabulary, grammatical or functional structures and whole sentences begin to emerge around the age of 30+ months. Entering the multi-word or Beyond Telegraphic stage, complex structures and the essential syntax of the grammar begin to evolve more and more, which develop into full language skills around the age of 6 years.

At 3 years old, about 80% of the child’s utterances are comprehensible to strangers, which shows that contextual cues are no longer necessary to understand the meaning of the sentences. Around the same age, children can form imperative sentences such as 'Give me my glass!'

Throughout the multi-word stage, children acquire the ability to use tense and agreement inflection correctly. The former refers to modifying verbs to indicate the present, past, or future tense; the latter matches the verb form with the person and number of the subject. However, during this phase of language acquisition, children may progress backwards. Let’s look at it with the example for the morpheme development: -ed, which declares the past-tense. Often, children learn and know irregular past tense forms and use them correctly. However, as they learn about the typical past tense marker -ed, children may use it incorrectly and say 'goed' or 'cutted' instead of 'went' and 'cut'. This over-regulation is a common linguistic phenomenon in a child’s language development.

Around the age of 4–5, children can speak in more complex structures and can, for example, use coordination (relationship of equivalence) sentences: 'He is tall, but I am taller.'

By 6 years old, having developed most language skills, a child may know 14'000 word meanings.

Having come to the end of the two lessons on language acquisition from birth to 6 years old, it is important to note that the development of language acquisition, of course, differs from child to child. What you have learned in lessons 1 and 2 are the general occurrences.

Final Thought

 

A child has acquired language and is able to speak roughly around the age of 6 years. However, even adults keep learning new words and adding to their vocabulary. So, what are your thoughts? Does language acquisition ever stop? Is there an end to the acquisition process?
