The word "kythed" is an archaic verb that means to show or make known. It is pronounced /kaɪðd/. The "y" in the spelling represents the sound /aɪ/ as in "my" or "thigh", while the "th" is pronounced as /ð/ in "then" or "father". The final "ed" syllable is pronounced as /d/, since the word is inflected in the past tense. Although the word is rarely used nowadays, it can be found in old literature and poetry.
