By the way, am I the only person who has absolutely no idea what sound this /ðʲ/ denotes?
How can you palatalise ð?
I'm disappointed, Kseniia: I thought, as a Russian speaker, you'd be able to palatalise anything.
The exact degree of palatalisation in Old Irish isn't really known, but it probably sounded something similar to the /ð/ in English
thee (as opposed to the /ð/ in
bother, though most English speakers probably don't notice the difference).
[And if anyone thinks it's complicated, try Irish numerals, you'll change your mind!]
Is that a hint?
Well, we don't have anything quite as crazy as changing the case for different numbers* (and in fact nouns used with numbers tend to resist changing for case whenever it would normally be required by the grammar) instead we have initial mutations (for anyone who doesn't know, that's where the sound at the beginning of a word changes).
*but wait...
So to continue the canine theme, the word
cú "hound" goes like this:
aon chú (though in speech it would normally be
cú amháin, where
amháin means "only" and the singularness is inherent in the noun)
, dhá chú, trí chú, ceithre chú, cúig chú, sé chú, seacht gcú, ocht gcú, naoi gcú, deich gcúSo, as you can see, the nominative singular form of the noun is generally used, the numbers 1-6 cause "lenition" (whereby plosive /k/ becomes fricative /x/), and the numbers 7-10 cause "eclipsis" (whereby voiceless /k/ becomes voiced /g/).
A few nouns have a dual form, used with the number 2, mostly referring to things that occur in pairs: hands, palms, ears, feet, shoes, etc., so
aon lámh, dhá láimh, trí lámh, "one hand, two hands, three hands", etc.
And a few nouns have a special plural form which is used with numbers from 3 upwards (and which is often different from the normal plural form), and in those cases the numbers 3-6 don't cause lenition, but prefix an h- if the word begins with a vowel, here's
uair "hour", normal plural
uaireanta:
1 uair, 2 uair, 3 huaire, 4 huaire, 5 huaire, 6 huaire, 7 n-uaire, 8 n-uaire, 9 n-uaire, 10 n-uaireWell, that's all straightforward enough; the fun really starts when you get above 10, partly because the noun is inserted between the units and the tens ("four hound teen"), and partly because there are two rival counting systems, one decimal (base 10, an Indo-European inheritance), and the other vigesimal (base 20, probably a pre-Indo-European vestige). So here are our hounds again:
aon chú dhéag, dhá chú dhéag, trí chú dhéag, ceithre chú dhéag, cúig chú dhéag, sé chú dhéag, seacht gcú dhéag, ocht gcú dhéag, naoi gcú dhéag, fiche cú (the
dhéag, "teen", becomes
déag after singular nouns ending in a consonant --
cúig chat déag "15 cats")
To illustrate the difference between the decimal and the vigesimal system, 33 hounds would be:
trí chú is tríocha "three hound and thirty" or
trí chú dhéag ar fhichid "three hound teen on twenty".
So that's how you count things in Irish. But of course, if it's
people you want to count, then you use a whole different set of numerals, with their own rules:
duine "one person",
beirt "two people",
triúr "three people",
ceathrar "four people",
cúigear "five people",
seisear "six people",
seachtar "seven people",
ochtar "eight people",
naonúr "nine people",
deichniúr "ten people",
aonar déag "eleven people",
dháréag "twelve people" (above 12 people you just use the normal numbers)
You can also use these numbers with nouns, which will then be in the genitive plural, and lenited after 2, so with
bean "woman":
bean "one woman",
beirt bhan "two women",
triúr ban "three women",
ceathrar ban "four women",
cúigear ban "five women",
seisear ban "six women",
seachtar ban "seven women",
ochtar ban "eight women",
naonúr ban "nine women",
deichniúr ban "ten women".
And if you're not counting people or things, but just counting, then the numbers have a slightly different form again:
a haon, a dó, a trí, a ceathair, a cúig, a sé, a seacht, a hocht, a naoi, a deichThere, it wasn't so complicated after all, was it?
