Inflected endings are primarily associated with indicating tense and number in words because they are grammatical markers added to base words that modify their meaning by providing additional information about time, aspect, mood, or quantity. For instance, adding "-ed" to a verb typically indicates past tense, while adding "-s" can signify pluralization in nouns.

This functionality of inflected endings is essential in constructing grammatically correct sentences, as they help convey the correct tense of a verb or the number of entities being discussed. This aspect is vital in understanding and using language effectively, as it allows for clarity in communication regarding when actions occur and how many subjects are involved.

The other options do not align with the core function of inflected endings. Indicating the meaning of a word alone pertains more to root words and derivational affixes rather than the grammatical adjustments made by inflections. Creating compound words involves combining whole words rather than modifying existing ones. Finally, changing a word's pronunciation does not reflect the role of inflected endings, which primarily involve spelling changes rather than phonetic alterations.
