What age group does the One-word Sentence stage generally occur in?

The One-word Sentence stage typically occurs between 12 to 18 months of age, marking a significant developmental milestone in language acquisition. During this stage, children primarily use single words to communicate their needs, wants, or observations. These single words serve as a complete thought or "sentence" for the child, such as saying "milk" when they want milk or "car" to express interest in a vehicle.

The choice indicating the age range of 10 to 13 months aligns closely with the onset of this stage, where infants begin to experiment with words. This stage is critical for building the foundation of expressive language skills, as it shows that children are beginning to understand the relationship between words and their meanings. This early form of communication eventually leads to the development of two-word and more complex sentences as children grow older.

In contrast, the other age choices represent different developmental milestones in speech and language. The age range of 5 to 7 years old typically corresponds to more complex sentence structures and grammatical development, while 3 to 5 years old links to further advancements in vocabulary and language complexity. The range of 18 to 24 months suggests the transition into more sophisticated language use but is not as precise as the earlier period of
