Allowed and Aloud are homophones because they have the same pronunciation, even though they mean completely different things.
Allowed can be an adjective or the past tense of the verb allow, and aloud is an adverb.
Homophones can be spelled in the same way or not, but they have to be pronounced the same way in order to be considered homophones.
