What role do context clues play in reading comprehension?

Context clues are essential for enhancing reading comprehension because they aid readers in deciphering the meanings of unfamiliar words through surrounding text. When a reader encounters an unfamiliar word, the information provided in nearby sentences or phrases can offer hints about the word's meaning, allowing for a smoother understanding of the overall passage. This skill is particularly valuable when reading complex materials where readers may not have prior knowledge of certain vocabulary.

The other options do not accurately capture the primary function of context clues. For instance, context clues do not detract from the central message or theme of a text; instead, they support readers in grasping that message more fully. While writing style can be influenced by context, it is not the main focus of context clues. Additionally, context clues are not meant to summarize the text; rather, they provide specific information that helps clarify individual words or phrases. Hence, the role of context clues is vital in promoting a better understanding of texts and enriching vocabulary skills.
