By what age can children usually say 7-10 words?

By 18 months, children typically develop the ability to say 7 to 10 words as part of their language acquisition process. This milestone reflects their growing vocabulary and the ability to communicate their needs and observations more effectively. At this age, children are transitioning from the initial stages of single words and may start combining words into simple phrases.

The development of vocabulary during this period is influenced by their exposure to language, interaction with caregivers, and their own cognitive development. Mastering a range of words allows them to express a wider array of thoughts and feelings, which is important for their social interaction and overall developmental progression. The increase in vocabulary show a child's cognitive development and understanding of their environment, emphasizing their readiness for further language growth as they approach the age of two.
