Here's why:
* Syntax is the study of how words are arranged in sentences and how they relate to each other grammatically.
* Word order refers to the sequence of words in a sentence, which often determines the meaning. For example, "The cat chased the mouse" has a different meaning than "The mouse chased the cat."
* Word relationships encompass how words connect to each other based on grammatical functions, such as subject-verb agreement, noun-adjective agreement, and the use of prepositions and conjunctions.
