Uuhh.
First of all, welcome! It's always nice to see someone learning Croatian
Basically, you have 2 main types of verbs: the one that ends in -ti and the other that ends in -ći. The first category (-ti) can be divided into subcategories like verbs ending in -ati, -(j)eti, -iti, -uti, -ovati, etc.; the second category stays as it is and has no subdivisions. The verbs that end in -ati (like
hodati [to walk]) will usually be conjugated like this:
1. ja hod
am2. ti hod
aš3. on/ona/ono hod
a1. mi hod
amo2. vi hod
ate3. oni/one/ona hod
ajuwith a few exceptions (which will be explained in the proper "paragraph").
Next, we have those that end in -iti (eg.
raditi [to work]) and -(j)eti (eg. vidjeti [to see]):
1. ja rad
im/vid
im2. ti rad
iš/vid
iš3. on/ona/ono rad
i/vid
i1. mi rad
imo/vid
imo2. vi rad
ite/vid
ite3. oni/one/ona rad
e/vid
eSo far no exceptions have crossed my mind, so my guess is that they are all regular, ie. take these endings.
But, the verbs that end in -čati, -žati and sometimes -jati (eg. trčati [to run], držati [to hold], stajati [to stand]) are conjugated like this (stajati -> stojim is a bit irregular, the others are regular. I think you'll just have to learn this by heart.).
The verbs that end in -uti (eg.
krenuti [to start moving])
1. ja kren
em2. ti kren
eš3. on/ona/ono kren
e1. mi kren
emo2. vi kren
ete3. oni/one/ona kren
uAlso, some verbs that end in -sati, -zati, -kati (probably some more) take these endings, but with a slight change in the stem in every person: pisati [to write] -> pi
šem, rezati [to cut] -> re
žem, skakati [to jump] -> ska
čem.
At the end, the ones that end in -ovati, -ivati belong to the last group (-em, -eš, -e,...), but they also undergo a change in the stem in every person: stanovati [to reside] stan
ujem, pokazivati [to show] -> pokaz
ujem. Some (not all!) verbs that end in -avati (eg. davati [to give] -> dajem, but pokušavati [to try] -> pokušavam) discard the whole ending, take a -j and then conjugate as krenuti.
As for -ći verbs, they, I dare say, always have some changes in the stem. However, after the changes, I think that each of them belongs to the last group. (eg. ići [to go])
1. ja idem
2. ti ideš
3. on/ona/ono ide
1. mi idemo
2. vi idete
3. oni/one/ona idu
To sum up, the first person singular has the answer to all your questions
Other persons undergo the same changes in the stem (if there are any) as the 1.sg. I hope this helped a bit (and didn't scare you off
)!
