What are examples of uninflected words?

Uninflected Words are those that do not change form to express different grammatical categories. Examples include the base forms of verbs (like "run" and "jump"), adverbs (such as "quickly" and "silently"), and certain nouns and adjectives in their simplest state (like "cat" and "happy"). Additionally, many conjunctions, prepositions, and pronouns can also be considered uninflected as they typically maintain their form regardless of context.
