To pronounce “althea,” break it down into syllables: al-thee-uh. The first syllable, “al,” is pronounced similarly to the “awl” used for sewing. The second syllable, “thee,” should be said with a long “e” sound, like the “ea” in “beat.” The final syllable, “uh,” has a short “u” sound, like the “u” in “but.” Practice saying each syllable separately before combining them to pronounce the word “althea.”
