hiems

• hiemps (usual but advised against by analogist grammarians)
• hyems

From Proto-Italic *hiem-, from Proto-Indo-European *ǵʰéyōm or similar.

Cognate with Ancient Greek χιών (khiṓn, “snow”), χεῖμα (kheîma, “winter, storm”), χειμών (kheimṓn, “winter, storm”), Persian زمستان (zemestân), Albanian dimër, Welsh gaeaf, Sanskrit हिम (himá), Hittite 𒄀𒈠𒀭 (gi-ma-an /⁠giman⁠/), Armenian ձմեռ (jmeṙ), and Proto-Slavic *zima.

• (Classical Latin) IPA^(key): [ˈhi.ɛmps]
• (modern Italianate Ecclesiastical) IPA^(key): [ˈiː.ems]
• Note the epenthesis of the homorganic stop [p] required to maintain the place of articulation of the stem-final /m/, as also in sūmpsī, temptō etc.
