I typically pronounce sedes as SED-ays.
What is the meaning of sedes?
Sedes is Latin for seat. Sedes may also refer to: a bishop's episcopal throne, also known as a cathedra.
How do you pronounce S's?
To make /s/, place the tip of your tongue lightly against the ridge behind your upper teeth (but do not touch the teeth). As you push air out of your mouth, squeeze the air between the tip of your tongue and the top of your mouth. You should feel some friction (resistance).
How do you pronounce es?
Despite how it's spelled, the -es ending actually sounds like /ɪz/. This is because it's a reduction. The -es ending on plural nouns or third person singular verbs will never be stressed. When we reduce sounds, they actually sound like the schwa sound /ə/ or the /ɪ/ sound.
