The ending -tion in e.g. ’information, civilisation, variation’ etc. is pronounced /ɧuːn/ in Swedish where the /ɧ/ is the sj-sound in e.g. sjunga. In a few words there is also a /t/ before it, like ’nation, motion, internationell’.

I'm not sure but I'd assume it wouldn't mean the same thing. Not sure if there's a Swedish equivalent of Board in that context.

Just use committee - it’s a direct translation.
