Substantivised and invariant assessment
Recover the referent and syntactic profile, then decide which word overtly carries agreement.
Mini-check
Decline больно́й as subject, animate object, dative recipient, and companion. Use столо́вая, бу́дущее, ро́дные, and да́нные in oblique cases. Distinguish lexical substantivisation from contextual ellipsis. Use ру́сский as person, language object, and по- adverb. Build and decline phrases with ми́ни, ма́кси, ха́ки, and ко́ми. Explain why part-of-speech labels may vary for invariant modifiers without making the course unusable.
