Here's why:
* Speech refers to the actual act of speaking, the sounds we produce, and the way we put those sounds together. It encompasses things like:
* Pronunciation
* Intonation
* Rhythm
* Speed of talking
* Language is a broader term that includes:
* Vocabulary (words)
* Grammar (how we put words together)
* Syntax (the order of words in a sentence)
* Semantics (the meaning of words)
So, while everyday speech uses language (words and grammar), it's the act of speaking itself that's being described when we talk about short sentences and simple vocabulary.
