The Comparative Method II

Let's say we have languages A, B, C, and D, and we want to know if they're genetically related. We start by taking a sample of basic vocabulary from each of them, and then compare those samples to each other. The best semantic categories from which to draw basic vocabulary includes pronouns (I, you, he, etc.), numbers (especially 1-10), human body parts (eye, head, heart, etc.), kinship terms (mother, father, etc.), natural objects and phenomena (sun, moon, water, fire, etc.), and very basic actions and states (see, know, die, etc.). Here's a small selection of possible vocabulary from languages A, B, C, and D.

A	B	C	D	English
ka	ka	ko	zimi	‘we’
nami	name	nom	soo	‘two’
paluma	paroma	polm	jai	‘eye’
litiki	redege	riik	enefo	‘mother’
kutusu	kodozo	kuts	vaha	‘water’
panu	pano	pon	haaz	‘eat’

In the comparative method, we're looking for regular phonological correspondences (which I'll abbreviate to RPCs). That is, given a set of words from each of the languages in question, we want to see if there is a regular pattern of phonemes that occurs between the items in the set. For example, look at the words for 'we' and 'water'. In all three of languages A, B, and C, these words begin with the phoneme k-. Likewise, in the words for 'eye', and 'eat', all the words in A, B, and C all begin with the phoneme p-. And in the word for 'two', we find all the words in A, B, and C beginning in n-. These are all examples of RPCs.
The phonemes don't all have to be the same to be regular. In the words for 'eye' and 'mother', language A has -l- whereas language B has -r-. Likewise, in 'we', 'two', 'eye', and 'eat, languages A and B have -a- where language C has -o-. These correspondences are just as regular as the k-, p-, and n- correspondences because they recur in multiple sets of words.
Now, what about language D? A close comparison between the different phonemes in language D's words and those of languages A, B, and C, reveals no meaningful correspondences; this suggests that D is not genetically related, or at least not closely genetically related, to languages A, B, and C, which, due to their numerous correspondences, seem to be very closely genetically related.
Now, a set of 6 words is not nearly enough to make conclusions about genetic relationships. Ideally, several hundred word sets should be selected, including not just nouns, verbs, or adjectives, but grammatical items such as plural markers on nouns, person, number, and tense markers on verbs, prepositions, different pronoun forms, etc. The more functional the items examined (those parts of the vocabulary which contribute more structure than meaning), the more solid the conclusions that can be drawn about genetic relationships.
Now, as an exercise for you the reader, here is a set of data from 5 European languages. Many of you will be familiar with at least some of these languages, but I'm going to change their spelling to make them slightly less recognizable, and also to reflect their true pronunciation a little better. Your task is to examine the word sets, look for regular phonological correspondences, and make a guess as to which languages are genetically related to which others (or which are more closely related to which, if it seems that they are all ultimately related).

A	B	C	D	E	English
ik	io	zhuh	ih	yo	‘I’
maan	luna	lyn	mont	luna	‘moon’
zyster	sorella	sur	shvester	ermana	‘sister’
vyyr	fwoko	fuh	foyer	fwego	‘fire’
akht	otto	wit	akht	ocho	‘eight’
vut	piede	pie	fus	pie	‘foot’
drinken	bere	bwar	trinken	bever	‘drink’

Bonus question: to which of the above do you think English is most closely related? What phonological correspondences can you name between English and that (or those) languages? Remember to concentrate on pronunciation, not spelling, since how a word is spelled may not reflect its pronunciation accurately.
