The Russian orthography was made simpler by unifying several adjectival and pronominal inflections, replacing the letters ѣ (Yat) with е, і (depending on the context of Moscovian pronunciation) and ѵ with и, ѳ with ф, and dropping the archaic mute yer, including the ъ (the "hard sign") in final position following consonants (thus eliminating practically the last graphical remnant of the Old Slavonic open-syllable system).
