Hey!

Homophones are the words which sound same but have different meanings, example "fete" ( festival) and "fate" (luck/chance).

Homonyms are the words which have same spelling but pronounced same with different meanings, example "Bow" ( tied on waist) and "bow" (front of boat).

Homographs are the words with same spelling and pronunciation but have different meanings  example "tear" (ripping off something) and "tear" ( liquid from the eyes)

Hyponyms are the sub divisions of broader units. There is no similarity in spelling and pronunciation. Example: rose is Hyponyms of flowers  and cat is Hyponym of animals.

Hope it helped to clear your delimma.
