No. Táim is the synthetic form, Tá mé is the analytic form, just as ithim is the synthetic form and itheann mé is the analytic form, and bailím is the synthetic form and bailíonn mé is the analytic form.
The contracted form "I'm" is slightly less formal than "I am" - that distinction doesn't exist between the analytic and synthetic forms in Irish.
i is the preposition "in".
táim i dtrioblóid is "am-I in trouble". It's not a question, though, because Irish puts the verb first. Also, "táim" is "I am" because first-person verbs have a synthetic form that fuse the "I" or the "we" to the verb.
No words got merged, aside from "táim", arguably. Did you follow the link? Eclipsis and lenition are sound changes that happen at the start of words depending on a combination of grammar and what sound came before it. Broadly, it's called initial mutation. It has nothing to do with merging two words into one.
No wonder kids want to give up. Not everyone is a linguistics major.
Is there a link for kids to understand this somewhere? I think thats what THIS 47 year old needs.
And we don't need sarcasm or judgement. Not everyone learns the same way.
If you don't know of a simpler way to understand, just scroll on.
At least 5 people found that link useful, judging by the upvotes. I doubt that they were all "linguistics majors". The link simply explains the historic basis for eclipsis, which developed from the way words run into one another, and has become formalized in the modern language even though the things that originally caused this sound change have been lost.
The link was posted in response to a question about whether the eclipsis in this example was caused by the sentence being in the present continuous tense, and it simply points out that no, eclipsis is not used for marking tenses.
You're right, "Not everyone learns the same way". So you shouldn't attack people for providing answers, even if you don't appreciate them, particularly if there is evidence that other people have found that response useful.
Not unless it also means "I forgot to pay the ESB bill" or "I think that flash was a speedcam" or "I just ran out of petrol, and I left my wallet at home" or "I just posted a sexist comment on twitter" or "I think I just poured bleach into the fabric softener compartment of the washing machine" or any of a million things that would get you in trouble.
None of the people that I've heard say "I'm in trouble" meant "I'm pregnant" - most of them were men, but the women weren't suggesting they were pregnant either.
So unless you can find a quote from Peig to suggest that Táim i dtrioblóid has some clear link to pregnancy, I think I'd have to say that no, it doesn't also mean "I am pregnant".
I don't mean idiomatically in the sense of "to have food" means "to eat food" and most people say it like that most of the time. I mean in the sense of it's a euphemism some people use because "pregnant" is a word they don't like to say, like "he passed" instead of "he died".
"I'm in trouble" means literally that most of the time and only occasionally can be used to mean "I'm pregnant".
It's not random, and it's called eclipsis.
