Like many western European languages we acquired a word for 'the' about 1500 years ago. It is rarer in the oldest Irish (from which comes modern Gaelic) and English, and absent from Latin.
Even of those that do have a word for the, some lack a word for a, including all the Celtic languages (apart from Breton which modified its own word for the to resemble the French word un).
It is this asymmetry that means that you may have to put a/an in the English, even before they have introduced any articles in Gaelic. D
Not all the literal translations are honoured. Part of the limitations of using an App not a real teacher or a mom lol. Pretty confusing at times trying to sort out the grammar of a Verb/ Subject/ Object language with prepositional pronouns! Orm = Air + Mi (on + me) Agam = Aig + Mi (At + Mi) sorry if you know this already.
I'm fed up ... I now tried "There is no skirt on me" and "There isn't a skirt on me" and "I have no skirt on me" and "I have not a skirt on me" ... but it STILL WANTS "I do not have a skort on" - WHAT IS WRONG with my attempts - please DO tell me ... I wanna a get it (LITERALLY) right !
I could not figure out for the life of me that she was saying "sgoirt". It sounded more like she was saying "scared" and I was baffled. All I could hear was "Chan eil ____ orm." I guess it must just be a dialectical thing, as there wasn't a distinctive "orsht" at the end of "sgoirt" the way she said it.
She was actually saying sgiort, so the t is broad. This is the way a broad rt is pronounced in many places, such a Skye. I would normally, but I think I would probably pronounce this word that is borrowed from English more like the English.
Because the vowel in the English word is quite an odd one, it would not be surprising if there is some confusion about how to pronounce this vowel in a borrowed word. So overall, I would say the pronunciation is quite reasonable and you certainly have to get used to the "rsht" sound, but this borrowed word is probably not a good word to learn Gaelic pronunciation rules from.
It does not say anywhere that the speaker is female. Anyone can wear a skirt, and anyone can be not wearing a skirt. Further, some people may take a skirt off for seduction, but others, who may not normally wear a skirt, may put one on for seduction. I know lots of people who normally wear trousers, but put a skirt on when they are going on a date. As it happens, I am not wearing a skirt at the moment.
