Answer from Copilot In linguistics, an **operator** is a functional element that affects the meaning or structure of a sentence. Operators can come in various forms, such as auxiliary verbs, quantifiers, or conjunctions. They play a crucial role in modifying sentences, forming questions, indicating negation, or expressing various tenses and aspects. **Examples**: - **Auxiliary Verbs**: "Can," "will," "must" (e.g., "Can you help?") - **Quantifiers**: "All," "some," "many" (e.g., "All dogs bark.") - **Conjunctions**: "And," "or," "but" (e.g., "He reads and writes.") Basically operators enable us to build complex sentences from basic sentences.
