a chairde

I was wondering if there is a special way to show respect in Irish. Like for instance in Spanish how you use the usted form when you speak to someone of higher rank or unfamiliarity. I just wanted to know if there is something like that which someone might use with someone he/she respects very much or holds in high regard.

Beir bua agus beannacht

You could say:

'a dhuine uasal' = O, exalted person, or

'a bhean uasal' = O, exalted woman, etc.

But you would only use this form in very formal settings, as when making a speech or when addressing an important, unfamiliar person in an informal setting.

what about "mister," 'miss' or 'missus'? "Mister So-and-so" for example... The only thing I've read is an t-uasal...does it go before the name or after and is there another way to do it?

As far as I'm aware, the referents in Irish for showing respect relate to warm and familarity, moreso than higher rank, at least since the Gaelic lords no longer exist to give deference to (The O'Neill etc), so one gets mo chroí an so on (my heart) a chairde and so on.

Perhaps the rural closeknit nature of the communities and common poverty made this so

Maybe cause it's traditional in Ireland to show respect through fondness and things rather than deference to status. Also the landlords were often absentees so there was no one to be deferential to.

Although in Scots-Gael, they use the plural form similar to french, eg. agaibh instead of agat to people you're sowing respect.
