Definition of the words content and function

Content
In phonetics and phonology, a "content word" refers to those words that have a complete lexical meaning and that provide substantial information to the message.
Examples:
1. The black cat jumps nimbly on the sofa
2. The graceful ballerina dances on the stage

Function
In phonetics and phonology, a function word refers to those words that have a grammatical role in the sentence and often do not provide a specific lexical meaning but do provide coherence.

2. She and I are going to the movies
Definition of falling and rising intonation

Falling intonation
It refers to an intonation pattern in which the voice lowers its tone at the end of a phrase or statement, which is often used for statements and questions.
Examples
1. I will go to the store later.
2. She finished her homework.
In both sentences, the tone of the voice tends to drop at the end, indicating a clear and definitive statement.

Rising intonation
It refers to a pattern of variation in the tone of the voice that rises at the end of a phrase or in certain parts of a sentence. It is used more in closed questions such as yes or no.
Examples:
1. Are you going to the party tonight?
2. I'm not sure what we should do.
