Sin always seems to have an é or a sé behind it, or the article - an madra sin, but I've also seen it standing by itself before without these, but I cant think of any examples to give for that. Sometimes I'm not sure on what should come before it, if anything. Could someone clarify the rules of sin for me again, please?
Sin can be used as a demonstrative pronoun (e.g. Ól sin [“Drink that”]), as an adjective (e.g. an madra sin [“that dog”]), or as an adverb (e.g. Bhí sé chomh hard sin [“It was that tall”]). It can seemingly stand alone when there’s an implied copula (e.g. Sin mo mhíniú [“That’s my explanation”]).
Just one little thing: For non-Ulster dialects, I believe a subpredicate is needed after sin with the implied copula.
Yeah I've come across that before. It needs to be is é sin or sin é in Connacht and Munster.
For your last example sin mo mhíniu, could that also be is é mo mhíniu sin or does the sin have to come before the subject in an identification clause?
Is é sin mo mhíniú
Basically you're equating 'that' (é sin) to 'my explanation' (mo mhíniú). Sin comes after the noun when used adjectivally - an míniú sin
