pisać-pisanie, jeść-jedzenie, what is the rule for jeść to jedzenie?

My guess is that it because it is an irregular verb it has no rule, it just is as it is.

Thanks in advance

pisać and jeść are verbs; pisanie and jedzenie are nouns.

Thanks, yes they are nouns but I would like to know how to change the verb jeść into a noun jedzenie, what is the rule?

I found another verb also, spaść that that I would like to turn into a noun. Hopefully the rule will be similiar to jeść to jedzenie.

spaść - spadanie

catsoldier - the irregularity comes from the history of the language (i.e. it is an etymological one)

jeść come from a verb root that looked like ed- (you see the root in edible which is a Latin loanword into English and equally is to eat a developement of the 'ed' verb root)

j is called a prosthetic consonant here (early Slavs didn't like ther words to start with 'e' for some reason)

so you got (j)ed-ti (that experienced contractions) - the form with -edz - is still retained in conjugation forms Oni jedzą. Oni jedli.

or spaść - spasienie

Spaść has 2 meanings:
spaść - spadać
spaść - spasać

Bzdura,

spaść - spadnięcie
spadać - spadanie

the noun is different for perfective and imperfective verbs e.g.:

robić - robienie
zrobic - zrobienie
jeść - jedzenie
zjeść - zjedzenie

etc.

Cinek

What if you take the third person plural (oni, one) of the present tense, and form from there? As mentioned above, jeść -> jedzą -> jedzenie.

Anyway there are some rules on when to use -nie (verbs in -ać, for example), when -onie, when -ęcie (verbs in -ąć) and when -cie (pić, myć,... -> picie, mycie,...). Check your grammar.

Thanks Magdalena, Gumishu, Zazulka, Cinek and Leopejo for your help.
