"Hi, Dewi Lingo."
Translation:S'mae, Dewi Lingo.
Is there any difference between 'S'mae' and 'Helo'? Is one of them formal and one informal, or are they both used in the same way?
You will hear both in common use. Sut mae? and its variants mean 'How are you/things?', and Helo means 'Hello/Hi' etc. Pretty much interchangeable, really, as in English.
