-야 • (-ya)

Post-vowel allomorphic form of -아 (-a, “hey”, vocative particle).
현우-야, 너 -가 물 엎질렀어? ― Hyeonu-ya, neo-ga mul eopjilleosseo? ― Hyeonwoo, did you spill the water?

나무-야, 넌 이름 -이 뭐 -니? ― Namu-ya, neon ireum-i mwo-ni? ― Hey, tree, what's your name?

For words formed by the suffix -이 (-i), the suffix is typically deleted and the vocative takes -아 (-a), e.g. 두꺼비 (dukkeobi, “toad”) > 두껍-아 (dukkeob-a, “hey, toad”).

-야 • (-ya)

Only used directly after the stems of -이다 (-ida, “to be”), either explicit or implicit, and its negative 아니다 (anida, “to not be”). If another suffix intervenes, the suffix reverts to -어 (-eo):
뭐 -였 -어? ― Mwo-yeoss-eo? ― What was this? (with past-marking -었- (-eot-))
Before -요 (-yo, politeness-marking particle attached to the intimate style), the form is again irregular -에요 (-eyo), and 이 -에요 (i-eyo) contracts to -예요 (-yeyo) following a vowel.
뭐-야 > 뭐 -예요? ― Mwo-ya > mwo-yeyo? ― What's this? (intimate) > What's this? (polite)
It cannot replace -어 (-eo) in its infinitive/connective sense. The copulas' equivalent to connective -어 (-eo) is -라 (-ra), although -어 (-eo) can still be used.

From Middle Korean -ᅀᅡ〮 (Yale: -zá), from Old Korean 沙 (*-sa); see the main entry for more.
