Final answer:
The terms thesis, pentad, and grammar are correctly matched with 'statement of direction and purpose', 'Who?', and 'rules for speaking and writing', respectively, demonstrating a clear understanding of these English language concepts.
Step-by-step explanation:
In this exercise, the goal is to match the term to its correct definition. The correct matches are:
- thesis - statement of direction and purpose
- main body - middle of the report
- pentad - Who?
- slang - rarely used in writing
- grammar - rules for speaking and writing
- trade - method of organization
- monotone - uninflected speech
- etymology - the study of word origins
- actor-agent - helped spread and develop language
A thesis serves as the central idea of a report or argumentative writing, explaining the scope and purpose of the text. The term pentad, from rhetoric and composition theory, refers to a method for analyzing motives and actions in communication, asking questions such as 'Who?' in relation to the actor or agent. Grammar encompasses the conventions and rules that dictate how language is structured for effective communication.
