[‎אַי‎] (, in Syriac in compounds as how ? WSG 120-2; compare Assyrian aiu, who? what?).

1. interrogative adverb where?
a. so with suffix ‎אַיֶּ֫כָּה‎ [a verbal form, see Sta§ 355 b. 3] Gen 3:9 ‎אַיּוֺ‎ Exod 2:20, poetry where is he? = he is nowhere Job 14:10; Job 20:7 (Jer 37:19 read Qr ‎אַיֵּה‎); ‎אַיָּם‎ Nah 3:17 (in indirect question) and the place thereof is not known, ‎אַיָּם‎ where they are. Idiomatically, with the suffix anticipating the noun to which it refers (Ew§ 309 c, compare DrSm. i. 21, 14) 2Kgs 19:13 ‎אַיּוֺ מֶלֶחחֲֿמָת‎ where is he, the king of Hamath? (|| Isa 37:13 ‎אַיֵּה‎) Isa 19:12; Mic 7:10. When used alone, or with other adverbs (see below), it is contracted to ‎אֵי‎ Gen 4:9; Deut 32:37; 1Sam 26:16; Prov 31:4 Qr. (The more usual form is ‎אַיֵּה‎.)
b. strengthened by the enclitic ‎זֶה‎ (see ‎זֶה‎, 4 ‎אֵיזֶֿה‎15 where, then ? (never of a person, except Esth 7:5 (late), & only once 1Kgs 22:24 [but see 2Chr 18:23] with a verb) Isa 50:1; Isa 66:1 (twice in verse); Jer 6:16, in indirect question 1Sam 9:18 in the phrase ‎אֵיזֶֿה הַדֶּרֶח ֗֗֗ ‎ where is the way (that) . . . ? 1Kgs 13:12; 2Kgs 3:8; 2Chr 18:23; Job 38:19 a. 24.

2. prefixed to other adverbs or pron., ‎אֵי‎ imparts to them an interrogative force: thus
a. ‎אֵיזֶֿה‎ which (of two or more)? only Eccl 2:3; Eccl 11:6 (late), in indirect question
b. ‎אֵימִֿזֶּה‎ whence ? (‎מִזֶּה‎ = hence; see below ‎זֶה‎) Gen 16:8 ‎אֵימִֿזֶּה‎ ‎בָאתְ‎ 1Sam 30:13; 2Sam 1:3; 2Sam 1:13; Job 2:2 in indirect question Judg 13:6; 1Sam 25:11 with substantive annexed 2Sam 15:2 ‎אֵימִֿזֶּה‎ ‎עִיר אַתָּה‎ literally whence, as regards city, art thou ? Jonah 1:8.
c. ‎אֵילָֿזֹאת‎ Jer 5:7 upon what ground ? (ᵑ9 super quo? how? With other adverbs, ‎אֵי‎ coalesces into one word, see ‎אֵיכָה‎, ‎אֵיכָכָה‎, ‎אֵיפֹה‎.
