I recently noticed that most languages have an irregular conjugation for the verb To be. I say almost because I don't know all languages, but the ones I've seen all have some irregularity sooner or later.
Here is a simple table providing some languages from Europe:
Note: if you find mistakes, let me know.
So far, I found only one language that fulfills the requirement, Quechua, with the verb "Kay":
1st — Ñoqa ka-ni
2nd — Qam ka-nki
3rd — Pay ka-n
1st — Ñoqanchik ka-nchik — inclusive
1st — Ñoqayku ka-niku — exclusive
2nd — Qamkuna ka-nkichik
3rd — Paykuna ka-nku
As you can see, the root (which is "ka-"), is always present. Excluding the ones from the list below, are there other natural languages that have the verb "to be" (meaning existence, not location) but regular?
- Asian languages
- All of the languages that have the same form for all the persons
- Languages that don't use this verb in the Present Affirmative form, e.g. Russian
