What skill can a child develop around 19 months to 2 years in terms of language?

Around 19 months to 2 years of age, a child typically begins to demonstrate significant language development milestones. During this stage, they often start to articulate a handful of words while also comprehending a larger vocabulary. This reflects an important aspect of language acquisition, where children are not just learning to speak but are also absorbing and understanding the language around them.

Saying a few words signifies the beginning of expressive language skills, while understanding many more words indicates cognitive growth and the ability to process language. This dual development of understanding and speaking is crucial, as it lays the groundwork for more complex language abilities that will develop in subsequent years.

In contrast, while other skills mentioned are part of language development, they may typically emerge either a bit earlier or later in the growth timeline. For instance, the ability to understand and obey simple commands is often evident even before 19 months, while joining in nursery rhymes and using a substantial vocabulary of 200 words usually occurs later. Thus, the correct choice accurately represents the typical language abilities seen in children within the specified age range.
