Irish (Munster): Conas tá tú inniu?
Irish (Connacht): Cén chaoi a bhfuil tú inniu?
Irish (Ulster): Cad é mar atá tú inniu?
Scottish Gaelic: Ciamar a tha thu an-diugh? (singular/familiar)
In Irish it's: Dia dhuit, caidé mar atá tú? / Dia dhuit, conas atá tú?/ Dia dhuit, cén chaoi a bhfuil tú?
Scottish:
Hallo, ciamar a tha thu? (familiar and singular))
Hallo, ciamar a tha sibh? (formal & plural)
