Upper Sorbian feminine nouns in the nominative singular end with -a or, much rarer, with a consonant. Those ones that end with -a may be both soft-stem (when the last consonant of the word's stem is bj, č, j, l, mj, nj, pj, rj, š, ć, wj or ž) and hard-stem (when the last consonant of their stem is b, c, d, h, ch, k, ł, m, n, p, r, s, t, w or z). Those which end with a consonant are hard-stem when they end with c, s or z; in all other cases they are soft-stem, even if its last consonant's softness may not be apparent in the nominative form (it becomes clear in cases formed with a diffrent than a zero ending). This group also includes some irregular nouns.
The following table shows the case endings of feminine nouns:
| singular | ||||
| stem: | soft | c z s | hard | velar |
| N | -a, -0 | -a | ||
| G | -e | -y | -i | |
| D | -i | -y | -’e | |
| A | -u, -0 | -u | ||
| I | -u | |||
| L | = dative | |||
| V | = nominative | |||
| dual | ||||
| stem: | soft | c z s | hard | velar |
| N | -i | -y | -’e | |
| G | -ow | |||
| D | -omaj | |||
| A | = nominative | |||
| I | = dative | |||
| L | = dative | |||
| V | = nominative | |||
| plural | ||||
| stem: | soft | c z s | hard | velar |
| N | -e | -y | -i | |
| G | -ow | |||
| D | -am | |||
| A | = nominative | |||
| I | -emi | -ami | ||
| L | -ach | |||
| V | = nominative | |||
The symbol -0 stands for a zero ending (an ending that is not represented by any sound in speech nor by any letter in writing).
An apostrophe before an ending (-’e) signals that some consonants when preceeding this ending alternate as shown below:
| consonant change | example | meaning |
| d > dź | woda > wodźe | water |
| t > ć | samota > samoće | lonliness |
| tr > tř | sotra > sotře | sister |
| ł > l | toboła > tobole | bag |
| ch > š | ropucha > ropuše | cress |
| h > z | dróha > dróze | street |
Whenever any other consonant preceeds an ending marked with an apostrophe, the consonant turns into its soft counterpart:
| consonant change | example | meaning |
| n > nj | žona > žonje | woman |
| w > wj | kruwa > kruwje | cow |
This ending in feminine nouns is only used with hard-stem and velar-stem nouns.
Some feminine nouns that in the nominative singular end with a consonant and have -ó- as their last vowel replace it with
| vowel change | example | meaning |
| ó > o | nóc > nocy | night |
The -y ending is proper for hard-stem nouns (both with Nom.sing. ending with -a and with a consonant) excluding those that have h, ch or k as the last consonant of their stem, which have here the -i ending.
The -e ending is used with all soft-stem feminine nouns.
Soft-stem nouns have the -i ending. Those of the hard-stem nouns that have c, s or z as the last consonant of their stem have the -y ending. The other hard-stem nouns have the -'e ending.
Those nouns which in the Nom.sing. end with -a have the -u ending, and those the Nom.sing. of which end with a consonant have the zero ending.
All nouns may have the -ow ending and the soft-stem ones may also alternatively have the -i ending.
The -ami ending is proper for hard-stem nouns and the -emi for those of the soft-stem type.
