Final -ę denasalizes to -e, and final -ą can be nasal -ǫ or -o in the third person plural present tense of verbs, -o in the accusative feminine singular of adjectives, numerals, and pronouns, and -om in the instrumental feminine singular of adjectives, numerals, and pronouns.
Initial a- may sporadically gain a prothetic h- or j-.
Infintives ending in -ść, -źć are usually simplified to -ś, -ź. sz is often realized as ś in loanwords, a process unrelated to masuration.
trz, strz, drz usually simplify to cz, szcz, dż.
The archaic -e of feminine genitive singular of soft stems is preserved.
