Correct spelling for the English word "doeth again" is [dˈə͡ʊθ ɐɡˈɛn], [dˈəʊθ ɐɡˈɛn], [d_ˈəʊ_θ ɐ_ɡ_ˈɛ_n] (IPA phonetic alphabet).
The word "doeth again" is a combination of two separate words: "doeth" and "again".
1. Doeth: It is an archaic form of the third person singular present tense of the verb "do". In Middle English and early Modern English, "doeth" was used to indicate that someone or something performs an action in the present. It derives from the Old English word "dǣþ" or "dōþ".
2. Again: This word comes from Middle English "agayn", which was adapted from Old English "onġēan". "Ġēan" means "against" or "opposite", and it was combined with the prefix "on-" meaning "on" or "towards" to create "onġēan".
