How does context affect the meaning of a word?

Context plays a crucial role in understanding the meaning of a word, particularly in discerning its intended use within a sentence or passage. The surrounding words, sentences, and overall situation provide essential clues that inform the reader about how a particular word should be interpreted.

For instance, the word "bark" can refer to the outer covering of a tree or the sound a dog makes. Without context, it’s ambiguous, but when placed in a sentence like "The dog began to bark loudly," the clues provided by the other words clearly indicate its meaning related to sound.

This understanding is vital for effective communication and comprehension, as many words have multiple meanings or nuances depending on their context. The other choices, while related to understanding words, do not capture the essential function of context in clarifying intended meaning through usage.
