agha
Agha,2 (m. nt.) [the etym. suggested by Morris J.P.T.S. 1889,200 (with ref. to M.I,500,which belongs under agha1) is untenable (to Sk. kha,as a-kha = agha,cp. Jain Prk. khaha). Neither does the pop. etym. of Bdhgh. offer any clue (= a + gha from ghan that which does not strike or aghaṭṭaniya is not strikeable DhsA.326,cp. Dhs. trsl. 194 & J.IV,154 aghe ṭhitā = appaṭighe ākāse ṭhitā the air which does not offer any resistance). On the other hand the primary meaning is darkness,as seen from the phrase lokantarikā aghā asaṁvutā andhakārā D.II,12; S.V,454,and BSk. aghasaṁvṛta M Vastu I.240,adj. dark M Vastu I.41; II,162; Lal Vist 552] the sky,orig. the dark sky,dark space,the abyss of space D.II,12; S.V,45; Vv 161 (aghasi gama,Loc. = vehāsaṁ gama VvA.78); J.IV,154; Dhs.638 (+ aghagata); Vbh.84 (id.).
--gata going through or being in the sky or atmosphere Dhs.638,722; Vbh.84. --gāmin moving through the atmosphere or space i. e. a planet S.I,67 = Miln.242 (ādicco seṭṭho aghagāminaṁ). (Page 5)
