天が下

Compound of 天 (ame, “heaven, heavens”) +‎ が (ga, Old Japanese possessive particle between two nouns) +‎ 下 (shita, “under, beneath”).[1]

Arose as the native Japanese kun'yomi for Middle Chinese compound 天下 (*ten *ha).[1] Compare also Japanese 天下 (​tenka), modern Mandarin 天下 (tiānxià).

Generally superseded by the term 天の下 (​ame no shita), using the more modern possessive particle の (​no).
