English
The teacher explains the idea.
The sentence names a person, an action, and the thing being communicated.
Communication can be a gesture, signal, or reaction. Language is more powerful because it uses repeatable patterns: symbols, rules, combinations, and shared expectations. Spoken, written, and signed languages all solve the same human problem: making meaning portable between minds.
