*ˀantā̆ - thou (masc. sg.) (CDG 32, Kogan 2009:66, Kogan 2015: 35)

CDG 32: ‘you’

Akkadian
atta - you (CAD A₂ 502, AHw. 87)
Ugaritic
ˀat - thou (DUL 120)
Hebrew
ˀattā - you (masc. sing.) (HALOT 102)
Jewish Babylonian Aramaic
ˀant - you (sg. m.) (DJBA 146)
Syriac
ˀat - you (sg.) (LSyr. 31, SL 66)
Mandaic
anat - thou (MD 24)
Maalula
hačč - you (m.) (GNMD 32)
The initial h-, whose origin is uncertain, is paralleled by MSA forms: Mhr. hēt, Jib. hɛt, Soq. ɛ (Kogan 2009:66).
Arabic
ˀanta - thou (masc.) (Lane 104)
Geez
ˀanta - you (CDG 32)
Tigre
ˀənta - thou (WTS 372)
No satisfactory explanation has been suggested for the shift *a > ə in the first syllable (Bulakh–Kogan 2013b:96).
Tigrinya
ˀanta - you (masc. sg.) (TED 1480)
Var. ˀatta (TED 1467).
Used only as a vocative form (by contrast with the innovative form nəssəka < *nafsə-kā used as a neutral 2 sg. m. pronoun, see Kogan 2009:66).

antä - thou (Leslau 1956:181)
Selti
atä - thou (EDG 102)
Zway
atä - you (masc. sg.) (EDG 102)
The loss of -n- (apparently, resulting from assimilation with the further reduction *ˀanta > *ˀatta > atä) is unusual for EthS and remains to be explained (Bulakh–Kogan 2013b:96). Compare Tna. ˀanta with its variant ˀatta.
