кофе • (kofe)
- coffee (beverage)
- coffee (beans)
- The word кофе is masculine, but is often informally treated as neuter: “горячее кофе”. Such usage is usually frowned upon by educated people.
- The word кофе is indeclinable, but may sometimes be declined into cases, usually for humorous effect: “налить кофю” (partitive case); “нет кофя” (genitive); “угостить кофем” (instrumental).
- Since the lack of declension is inconvenient, the diminutive forms of кофе, кофеёк and кофей, are often used.
- As of September 1, 2009, the Russian Ministry of Education has decided that кофе may be acceptably treated as either masculine or neuter.
