The correct choice identifies a key characteristic of suffixes in the context of word formation. Suffixes are defined as letters or groups of letters that are added to the end of a base word. This process alters the meaning of the base word or changes its grammatical function, such as by transforming a noun into an adjective or a verb into a noun, thereby expanding its usage in language.

For instance, adding the suffix "-ing" to the verb "run" creates the word "running," which denotes the action of running in progress. This illustrates how suffixes play a crucial role in modifying both meaning and grammatical structure within the English language.

In contrast, the other choices outline misconceptions about suffixes. The idea that they are always added at the beginning of a word refers to prefixes, not suffixes. Limiting suffixes solely to changing a word's tense overlooks their broader applications in altering word forms. Lastly, while suffixes can contribute to the formation of new words, they do not function in creating compound words, which typically involve combining two complete base words.
