Resumen de Indo-European syntax in disguise: the Greek type ἱππεύς and related formations
The Greek noun suffix -ευς is analyzed as a hypostatic u-stem formation based on an instrumental in *-eh₁- with close cognates in Lithuanian -ius and Armenian -oyt‘ < *-eh1u-ti-. Thus the type reflects the inherited predicative use of the instrumental case also known from the Old Indic cvi-constructions and the Latin type rubefaciō.
