Des Moines, the capital metropolis of Iowa, is pronounced as “duh MOIN.” The title is of French origin and means “the monks.” The town was based in 1843 by French fur merchants and missionaries, who named it after the Des Moines River, which flows by town.
The pronunciation of Des Moines may be difficult for non-native English audio system, because the “oi” sound will not be frequent in English. The “oi” sound is pronounced just like the “oy” sound in “boy” or “toy.” You will need to pronounce the “s” on the finish of the phrase, as it’s not silent.
