For (any) neuter nouns ending in -vowel+um/on (for example štúdium, ganglion) there is actually a 5th paradigm ('''štúdium'''), which is declined like mesto except that the -um- / -on- is omitted in all cases except N sg and A sg., L sg ends in -u (štúdiu), and G pl in -í  (štúdií).

'''Notes on mesto:'''
*Latin and Greek neuter nouns ending in consonant + -um/-on (for example fórum, epiteton) are declined like mesto, except that the -um/-on is omitted in all cases except N sg and A sg (for example, N sg and A sg: publikum, G sg: publika, D sg: publiku etc.);
*in the G pl of some nouns, an ie/ e / o / á / (rarely é) is inserted in the last syllable of the stem (for example clo – ciel, mydlo –mydiel, zvieratko – zvieratiek, jedlo – jedál, vrecko – vrecák/vreciek, vlákno – vláken/vlákien, číslo – čísel / čísiel, lajno – lajen, lýtko – lýtok, teliesko – teliesok;
*in the G pl of some nouns, in the last syllable of the stem, the a / i / y / u / ä / e / o / syllabic r / syllabic l (without an acute or a preceding i) is changed into á / í / ý / ú / ia / {{not a typo|ie}} / ô / ŕ / ĺ respectively (kladivo – kladív, zrno – zŕn).

'''Notes on srdce:'''
* In the G pl of some nouns, an ie/e is inserted in the last syllable of the stem (for example citoslovce – citosloviec, okience – okienec, vajce – vajec);
* In the G pl of some nouns, in the last syllable of the stem the a / i / y / u / ä / e / o / syllabic r / syllabic l (without an acute or a preceding i) is changed into á / í / ý / ú / ia / {{not a typo|ie}} / ô / ŕ / ĺ respectively (plece – pliec, srdce – sŕdc, slnce – sĺnc).

'''Notes on vysvedčenie:'''

'''Notes on dievča:'''
* The -a- at the beginning of all endings is replaced by ä after a labial consonant, i.e. p/b/m/f/v (for example žrie'''b'''ä – žrie'''b'''äťa – žrie'''b'''äťu...);
* Most nouns can take both the -at- endings and the -enc- endings in the plural (for example dievča, húsa, bábä), some nouns however take only the -at- endings (for example knieža, zviera, mláďa) and some nouns only the -enc- endings (for example kura). The following nouns do not take the -en- in the alternative plural endings: prasa (N pl prasatá/prasce, G pl prasiat/prasiec), teľa, šteňa.
