Cooperative play is indeed a stage that significantly boosts a child's language development. This is because it involves a lot of interaction, communication, and negotiation between children. They learn to express their thoughts, ideas, and feelings, and also learn to understand the same from others.

There are several signs or signals that indicate a child's language is developing during cooperative play:

1. Vocabulary Expansion: Children start using new words that they learn from their peers. They also begin to understand the context in which to use these words.

2. Sentence Construction: Children start forming more complex sentences. They begin to use conjunctions, prepositions, and adverbs, indicating a grasp of sentence structure.

3. Conversational Skills: Children engage in back-and-forth exchanges, respond to what others are saying, and wait for their turn to speak. This shows they are understanding the dynamics of conversation.

4. Problem Solving: Children start using language to solve problems during play, like deciding roles in a pretend game or negotiating rules. This shows they are learning to use language as a tool for thought.

5. Understanding and Expressing Emotions: Children begin to talk about their own and others' feelings, showing an understanding of emotional language.

6. Asking Questions: Children's questions become more complex, moving beyond just 'what' and 'why', indicating curiosity and a deeper understanding of language.

7. Storytelling: Children start to create and tell stories during play, showing an understanding of narrative structure and sequence.

These signs indicate that cooperative play is helping children develop their language skills.
