Unlike most other Slavic languages, so-called "yer tensing" (the special development of > and > for some yers preceding ) did not happen in Russian, nor was later lost. Yers preceding developed as elsewhere; when dropped, a sequence "Cʲj" developed, which is preserved as such only in Russian. (*Cʲj > "CʲCʲ" in Ukrainian and Belarusian; elsewhere, it generally merged with *Cʲ or *Cj, or the was dropped early on.) The main exception to the lack of lack of yer tensing is in long adjectives, where nominative becomes expected ("oj") only when stressed, but yer-tensed ("yj") elsewhere, and nominative (which is never stressed) always becomes yer-tensed ("ij").
