A question that our B&B guests ask often: « How is pronounced Reims ? »
French is not an easy language and the name Reims is quite special !
It is pronounced [ʀɛ̃s] ou /ʁɛ̃s/ the M is almost silent.
Just say it ‘rins’ and it should do it ;)
Reims inhabitants are called ‘Rémois’ and ‘Rémoise’ [Remwa] , [Remwaz]
An old spelling of Reims is Rheims but it was used mostly in the British Isles and is barely used nowadays.
