Different sentence structure in questions?
Something that I noticed in English quite a bit is that questions and statements have different structure lots of the time ("Who was it?" instead of "It was him."). I'm wondering if there's anything similar for Irish, because I frequently mess up with the differences between statements and questions and I probably wouldn't be able to tell the difference most of the time if it weren't for end punctuation.
However, the differing question structure in English, now that I think on it, may just be a side effect of inverted sentence structure, so I guess that the real question I should be asking is one of whether inverted sentence structure, or something of the kind, exists in Irish.
Questions in Irish will begin with an interrogative word — either a verbal particle (e.g. an, ní, etc.), an interrogative form of the copula (e.g. an, nach, etc.), a pronoun (e.g. cé), an adverb (e.g. conas), or an adjective (e.g. cad é). An interrogative verbal particle precedes the verb, but otherwise preserves the usual word order in non-copular statements. The interrogative forms of the copula replace the statement forms, and the same variety of sentence orders in copular statements can appear in their interrogative versions. The interrogative pronouns/adverbs/adjectives appear in interrogative copular sentence form, since they generally represent an implied copula.
In summary, inverted sentence structure is only present when emphasis is placed on a particular part of a sentence, and does not happen by default in interrogative sentences.
