*Numerals. (b) Ordinal Numbers*.

98*a* The ordinal numbers from 2 to 10 are formed from the corresponding cardinals by adding the termination ־ִי (§86*h*), before which another ־ִי also is generally inserted between the second and third radicals. They are as follows: שֵׁנִי *second*, שְׁלִישִׁי, רְבִיעִי (like רֶ֫בַע, רֹ֫בַע, רִבֵּעִים, without the prosthetic א, which appears in אַרְבַּע, &c.), חֲמִישִׁי or חֲמִשִׁי (which, according to Strack, is always to be read for חֲמִשִּׁי), שִׁשִּׁי, שְׁבִיעִי, שְׁמִינִי, תְּשִׁיעִי, עֲשִׂירִי. The ordinal *first* is expressed by רִאשׁוֹן (cf. §27*w*), from רֹאשׁ *head, beginning*, with the termination וֹן (§86*f*). On the use of אֶחָד as an ordinal in numbering the days of the month, cf. §134*p*; in such cases as Gn 1^{5}, 2^{11}, the meaning of *first* is derived solely from the context.

98*b* The feminine forms have the termination ־ִית, more rarely (and only in the case of 3 and 10) ־ִיָּה. They are employed also to express fractions, e.g. חֲמִשִׁית *fifth* or *fifth part*, עֲשִׂירִית and עֲשִֽׂירִיָּה *tenth part*. Side by side with these, in the same sense, there are also forms like רֹ֫בֵע and רֶֹ֫בַע *a quarter*, חֹ֫מֶשׁ *a fifth part*, and with the afformative וֹן, עִשָּׂרוֹן (plur. עֶשְׂרוֹנִים) *a tenth part*; these are to be regarded as abstracts, and are denominatives from the cardinal numbers. Cf. finally שָׁבוּעַ ἑβδομάς, *a week*; עָשׂוֹר *a decade* (of days), and also the *tenth day*.

On the expression of the other relations of number, for which the Hebrew has no special forms, see the Syntax, §134*q* and r.
