Why a special-noun module is justified
Most nouns fit productive families; a smaller set selects an irregular stem, an adjectival paradigm, no visible declension, or a restricted construction-specific form.
| System | Examples | Learner action |
|---|---|---|
| mixed / irregular stem | вре́мя, мать, путь | store diagnostic forms |
| suppletive number | челове́к - лю́ди | store singular and plural stems |
| indeclinable | метро́, пальто́ | read case from syntax/agreement |
| adjectival noun | рабо́чий, столо́вая | use adjective endings |
| proper-name rule set | Илья́, Ивано́в, Со́чи | classify before declining |
| restricted extra form | в лесу́, вы́пить ча́ю, Маш! | learn construction and register |
