раз-

• разо- (razo-) (before certain consonant clusters)
• рас- (ras-) (before voiceless consonants)

Borrowed from Old Church Slavonic [Term?], from Proto-Slavic *orz-. Doublet of роз- (roz-), the inherited East Slavic form.

• IPA^(key): [rəz]

раз- • (raz-)

1. (used with verbs) asunder, apart
2. (used with verbs) dis-, di-, un-

   ‎разо- (razo-) + ‎-йти́ (-jtí, “to go”) + ‎-сь (-sʹ) → ‎разойти́сь (razojtísʹ, “to go asunder, to disagree”)

   ‎раз- (raz-) + ‎дева́ть (devátʹ, “to put”) → ‎раздева́ть (razdevátʹ, “to undress”)

3. (used with verbs) enlarged action

   ‎раз- (raz-) + ‎рабо́тать (rabótatʹ, “to work”) → ‎разрабо́тать (razrabótatʹ, “to develop, to work out”)

4. (used with verbs) with reflexives, giving rein to

   ‎раз- (raz-) + ‎говори́ть (govorítʹ, “to talk”) + ‎-ся (-sja) → ‎разговори́ться (razgovorítʹsja, “to talk up a storm”)

   ‎не (ne, “not”) + ‎рас- (ras-) + ‎слы́шать (slýšatʹ, “to hear”) → ‎не расслы́шать (ne rasslýšatʹ, “to not quite hear”)

When stressed, раз- (raz-) normally changes into ро́з- (róz-), and the voiceless variant рас- (ras-) correspondingly becomes ро́с- (rós-):

• разда́ть (razdátʹ, “to distribute”) → past passive participle ро́зданный (rózdannyj)
• расписа́ть (raspisátʹ, “to paint, to decorate”) + -ь (-ʹ, noun-forming suffix, which normally causes stress to move onto a prefix) → ро́спись (róspisʹ, “painting, mural”)
