According to Brown's Morphemes Stage 3, which morpheme is learned between 36-42 months?

Brown's Morphemes Stage 3 focuses on the language development milestones for children typically between the ages of 36 and 42 months. During this stage, children begin to acquire more complex grammatical structures. The correct morpheme that is learned during this period is the irregular past tense.

Children in this age range start to understand that verbs can change form depending on the tense, and they begin to utilize some irregular verbs as they refer to past events. This development is crucial because it marks a shift from using simpler sentence structures to more varied and complex forms of communication, which are essential for conveying a wide range of ideas and timelines.

In contrast, the other options reflect morphemes learned at different stages. The regular plural -s is generally acquired earlier, around 24 to 30 months, while the present progressive -ing is typically learned around 19 to 28 months. Articles are usually introduced a bit later in development. Each morpheme has a specific timeline for acquisition, highlighting the progressive nature of language development in young children.
