When do you use anns versus ann?
Hey, there is a sticky post on the forum with the grammar notes. They will generally explain better than I could on here. :) Anns before words that start with a "the" as some countries do in Gaelic.
Short version: 'anns + definite article' is "in the", confusing for learners is that 'ann an/am' is simply "in" - the 'an' there is not an article, just part of a two word phrase which translates to "in".
