Russian orthography was made simpler and easier by unifying several adjectival and pronominal inflections, replacing the letters ѣ (Yat) with е, ѳ with ф, and і (depending on the context of Moscovian pronunciation) and ѵ with и. Additionally, the archaic mute "yer" became obsolete, 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).
