Which semantic characteristic is typically observed in children with SLI?

The correct choice highlights that children with Specific Language Impairment (SLI) often exhibit a delayed onset of their first word. This characteristic underscores one of the primary challenges faced by these children in their language development. Typically, children begin to produce their first words between 10 and 14 months of age. However, children with SLI may not reach this milestone until later, indicating a significant delay in their expressive language skills.

This delay can impact their overall communication abilities and can often be one of the earliest signs that prompts parents and practitioners to seek assessments and intervention. Understanding this characteristic is crucial for early identification and support, as interventions can be more effective when initiated early in a child's development.
