How can context clues like but not or also help a reader better understand an unknown word?

Context clues such as "but," "not," and "also" provide hints about the meaning of an unknown Word by illustrating relationships between ideas. For instance, "but" may indicate a contrast, suggesting that the unknown Word has a different or opposing meaning to the preceding idea. Similarly, "not" signals negation, helping readers infer what the Word does not mean, while "also" implies addition, indicating that the Word likely shares similarities with previously mentioned concepts. These clues enable readers to make educated guesses about unfamiliar vocabulary based on the surrounding text.
