πρᾶος

• πρᾷος (prâios)
• πρᾱῠ̈́ς (prāǘs)
• πρηΰς (prēǘs) — Ionic

Probably from earlier πραΰς (praǘs), regularly derived from Proto-Indo-European *preh₂-i-u-, from *preh₂- (“to like, feel friendly/well-disposed”). Cognate with Latvian prieks (“joy”), Old Church Slavonic приꙗзнь (prijaznĭ, “friendship”), Sanskrit प्रिय (priya, “dear, beloved”), Welsh rhydd (“free”), Old English frēo (English free.)

     hòs Surakóssaisi némei basileùs praǜs astoîs

     the king who rules Syracuse, gentle to his citizens

2. tame
   • 430 BCE – 354 BCE, Xenophon, Anabasis 1.4.9:

     τὸν Χάλον ποταμόν, ὄντα τὸ εὖρος πλέθρου, πλήρη δ’ ἰχθύων μεγάλων καὶ πραέων

3. mild
   • 428 BCE – 347 BCE, Plato, Laws 888a:

     πῶς τούτους ἄν τις ἐν πρᾳέσι λόγοις δύναιτο νουθετῶν

     How, I ask, can one possibly use mild terms in admonishing such men?

In Attic, Tragedy, and Comedy, πρᾶος is used in the singular, except that the feminine is always πραεῖα. Forms from πραΰς (Ionic πρηΰς) are used in Epic and Lyric poetry, as well as in Xenophon, the Septuagint, Polybius, etc.
The iota subscript (viz. πρᾷος) is written in manuscripts, but not inscriptions. **πρᾳΰς does not appear. This adjective is not used in Homer.
