This said, you still can use analogy: the pronunciation /arka/ would be replaced by /arxa/, due to the presence of the form /arx/, especially if other nouns would regularly have /x/ even when endings are added. This would level out the "irregularity". It's something which happens often in languages. To give you an example, let's take the Latin declension of the word |honor|: honour :)) . At first, the word was [honos], with regular declension: [honos], [honosEm], etc... At one point, a sound change occured: [s] -> [r] / V_V (or: "[s] became [r] between vowels"). It affected [honos] like any other word, only when the [s] was intervocalic! So suddenly the declension of that noun became [honos], [honorEm], etc... thus becoming "irregular". It seems that the speakers didn't like this irregularity, and levelled it out, and by the process of analogy (probably influenced by nouns like [orator], accusative [oratorEm], which had final [r] even before the sound change) created the nominative form [honor] to replace [honos], thus reobtaining a regular noun. You could use such a feature to "regularise" your nouns, but it works only if the speakers realise that there are different sounds (in your case, /x/ must be a phoneme, not just a phone [x] which exists only as the realisation of a final /k/ (and here I obtain a nice connection to the previous mail I sent, which IIRC was to answer another question of yours :)) ). The fun part about analogy is that it's an irregular process, i.e. you can have it used on some words and not others, without even needing an explanation for the discrepancy!! Isn't that nice? :))) Christophe. http://rainbow.conlang.free.fr Take your life as a movie: do not let anybody else play the leading role.
