Proto-Indo-European

    Etymology 1

    Suffix

    *-ós

    1. Forms possessive adjectives from nouns.
      *wétos (year) + ‎*-ós → ‎*wetsós (of a year)
    Usage notes
    • The root vowel is usually identical to that of the base noun, but sometimes the root vowel is zero-graded.
    • The suffix vowel on the other hand is usually deleted when the possessive suffix is attached.
    • Very commonly stacked on top of neuter *-es- stem nouns.
    • Examples of non-*-es-stem possessive thematic adjectives across Indo-European include:

    Suffix

      1. Creates agent nouns from verb stems, denoting someone or something that performs that verb's action.

    Reconstruction notes
    • See Nussbaum (2017)[1] for a detailed account.
    • Agentive nominals of this type are often compared to Ancient Greek τομός (tomós, cutting) in the literature. Patientive nominals of this type, on the other hand, include Ancient Greek φορός (phorós).

    Etymology 3

    Closely resembles, but is not identical to, the root o-grade counterpart *(o)-ós. Both formations can be found side-by-side for several roots. Nussbaum posits that both of these adjective formations are derivatives of *(ó)-os formations.[2]

    Villanueva Svenson, who proposes that e-grade thematic verbs originated as conversions of λευκός (leukós) adjectives to verbs, wonders if these e-grade adjectives were originally barytone, but later became oxytone under the influence of *(o)-ós.[3]

    Suffix

    *(e)-ós

    1. Forms adjectives from verbal roots.
      *lewk- (to shine) + ‎*-ós → ‎*lewkós (bright, shining)
    Usage notes

    These adjectives are known as λευκός (leukós) adjectives in the literature. They lost productivity in every branch other than Germanic, but most Indo-European branches do have relics of this formation.

    Etymology 4

    Suffix

    *(e)-ós

    1. Forms adjectives or nominals of appurtenance to bases.
      *dyew- (sky) + ‎*-ós → ‎*deywós ((god) of the sky)
    Usage notes

    These nominals are known as vṛddhi in Indo-Europeanist literature. The *e that the base incorporates in such formations is not necessarily the e-grade of the root; the *e is instead located after the first consonant of the root, no matter the root shape.
