Here's a breakdown of how this concept applies:
* Internal words are words that are part of a sentence, phrase, or clause. They are not stand-alone units.
* External words are words that are not part of a sentence, phrase, or clause. They might include titles, headings, labels, or other elements that provide context or organization.
Examples:
* Internal words: In the sentence "The cat sat on the mat," the words "cat," "sat," "on," and "mat" are internal words.
* External words: The title "Cat on the Mat" is an external word.
