What is an apatya‑pratyaya?

An apatya‑pratyaya is a patronymic affix—a taddhita suffix used to

Pāṇini introduces this category under the rule tasyāpatyam

(“that whose offspring/descendant is…”) at P. 4.1.92, which 

governs the formation of such derivatives.

Common apatya affixes

The grammar tradition lists several taddhita suffixes used in

the sense of apatya. The supplied results describe them

in detail

:

• aṇ (अण्) — the default apatya affix when no other is specified.
  • Causes vṛddhi of the first vowel of the base.
  • Example: upagu → aupaguva (“descendant of Upagu”)

    .
• iñ (इञ्) — used after bases ending in short a.
  • Also causes vṛddhi.
  • Example: Daśaratha → Dāśarathi (“descendant of Daśaratha”)

    .

These affixes are applied according to Pāṇini’s taddhita rules and 

undergo regular phonological operations (vṛddhi, guṇa, it‑letter deletion, etc.).

Semantic function

An apatya‑pratyaya expresses:

• biological descent (“child of X”),
• lineage or gotra affiliation,
• patronymic naming, especially in classical literature and
• ritual texts.

Thus, words like Pārtha (“son of Pṛthā”), Vainateya, or 

Dāśarathi are classic examples of apatya‑derivatives.

Summary

• Apatya = “offspring, descendant.”
• Apatya‑pratyaya = a taddhita suffix meaning “descendant of X.”
• Common affixes: aṇ, iñ, ḍhak, each with specific phonological effects.
• Used widely in Sanskrit to form patronymics and lineage names.
