The word "Alitheea" is spelled using the International Phonetic Alphabet as /ælɪθiːə/. The first sound, /æ/, is the "a" as in "cat." The following sequence, /lɪθ/, represents the "lith" sound, which is a bit like "lif" but with a "th" sound in the middle. The final two sounds, /iːə/, are the "ee-uh" dipthong, as in the word "idea." Taken together, this gives us the pronunciation of "Alitheea."
