In the sentence 'The dog barks loudly', which part of speech is 'barks'?

• A. Noun
• B. Verb
• C. Adjective
• D. Adverb

Answer: (B)

The action word in this sentence is the main predicate: it tells what the dog does. The word barks functions as a verb because it expresses the action and shows present tense with a singular subject (the dog barks). It’s not a noun because it doesn’t name anything, not an adjective because it doesn’t describe a noun, and not an adverb because it doesn’t modify a verb, adjective, or another adverb. The word loudly, meanwhile, is the adverb describing how the barking happens.
