Cardinals and Ordinals

Cardinal	Meaning	Ordinal	Meaning
1: oinos, oina, oinom; sem-	one	prwo	first
2: dwo, dwa, dwoi	two	entero / eltero, dwito*	second
3: trejes, tris(o)res, tri	three	trio, trito	third
4: qetwor	four	qturo, qetwrto	fourth
5: penqe	five	pnqo, penqto	fifth
6: s(w)eks	six	seksto	sixth
7: septm [sept'm]	seven	septmo	seventh
8: okto(u)	eight	oktowo	eighth
9: newn [new'n]	nine	nowno, neunto	ninth
10: dekm [dek'm]	ten	dekmo, dekmto	tenth

NOTE 1. The words for one are oino-,one, only; as well as sem-, one, together, united, which refers to the unity considered as a whole, and appears usually in word compounds, as in seme, at once, at the same time, semel, one time; semle, formerly, once, etc. The root oi- (which gives oino-) can also have its -rare- compounds, as in oiuos, one alone, unique.

NOTE 2. The forms for two alternate dwo/do, with duw-/du-. Alternating forms of four are qetwor, qtwor, qetur, qetr, qetwr. The forms for six are seks (ger., lat., bsl.) or sweks (gr., cel.).

NOTE 3. The Ordinals are formed by means of the thematic suffix -o, which causes the syllable coming before the ending to have zero grade. This is the older form, which is combined with a newer suffix -to. For second, a word meaning other is used, although the Latin form seqondhos (see § 7.2.8, 3) could also be used for some expressions, as seqondharios; and also a logic reconstruction dwito. For seven and eight there is no zero grade, due probably to their old roots.

2. The forms from eleven to nineteen are formed (in i.-i., gr., lat., cel., ger. and arm.) by copulative compounds with the unit plus the number ten.

Cardinal	Ordinal
11: oindekm	oindekmo
12: dwodekm	dwodekmo
13: tridekm	tridekmo
14: qetwrdekm	qeturdekmo
15: penqedekm	penqedekmo
16: seksdekm	seksdekmo
17: septmdekm	septmdekmo
18: oktodekm	oktodekmo
19: newndekm	newndekmo

3. The tens are formed with the units with lengthened vowel or sonorant and the numeral ten.

Cardinal	Ordinal
20: (d)wikmt	(d)wikmto
30: trikomt	trikomto
40: qetwrkomt	qetwrkomto
50: penqekomt	penqekomto
60: sekskomt	sekskomto
70: septmkomt	septmkomto
80: oktokomt	oktokomto
90: newnkomt	newnkomto
100: kmtom	kmtomto
1000: tusnti, gheslo	tusntito

NOTE. The Europaio indeclinable form for thousand is tusnti [tus'nti:] (as in ger. and bsl.), while gheslo- (as in gr., oi., and possibly lat.) is a declinable adjective, as the one which probably forms milliard, million, billion, and so on.

4. The hundreds are made as compounds of two numerals, like the tens, but without lengthened vowel. The thousands are made of the numerals plus the indeclinable tusnti:

Cardinal	Ordinal
200: dwokmtom	dwokmtomto
300: trikmtom	trikmtomto
400: qetwrkmtom	qetwrkmtomto
500: penqekmtom	penqekmtomto
600: sekskmtom	sekskmtomto
700: septmkmtom	septmkmtomto
800: oktokmtom	oktokmtomto
900: newnkmtom	newnkmtomto
2000: dwo/dwei/dwo tusnti	dwo/dwei/dwo tusntito
3000: trejes/trisores/tri tusnti	trejes/trisores/tri tusntito

NOTE. In ger. the hundreds are compounds made of a substantive of hundred, but we have chosen this - for us more straightforward - form, given in lat., ita., bsl. and gr.

5. The compound numerals are made with the units in the second place, usually followed by the copulative qe:

wikmt oinaqe / wikmt oina, twenty (and) one [f.]; trikomt qetworqe / trikomt qetwor, thirty (and) four; etc.

NOTE. The forms with the unit in the first place are also permitted, but most of the European languages think about numeric compounds with the units at the end. So, oinoswikmtqe, qetwortrikomtqe, etc. are also possible in this system, always written as one word.
