Verb classes: reading the present from the infinitive
The lesson “Present tense” gave you three sets of endings, -am, -im and -em, and three model verbs: čitati → čitam, raditi → radim, pisati → pišem. One practical question was left open: you meet a new verb and know only its dictionary form, the infinitive (the “to …” form). Which class is it, and what is its present stem? Take čitati and pisati: both end in -ati, yet they conjugate differently. This lesson is a map that takes you from the infinitive to the present.
Often the end of the infinitive tells you. See -ovati, expect -ujem; see -nuti, expect -nem; see -iti, and it is almost certainly -im. But at -ati and -eti the road forks, and the infinitive alone cannot tell you which way: there you have to know the verb.
The map: end of the infinitive → present stem
Here is the whole map in one table: on the left what you see in the dictionary, on the right what you get in the present.
The safe anchor: -iti almost always gives -im
Verbs in -iti go into the -im class with hardly any exceptions, and you get the “I” form by swapping -ti for -m: raditi → radim, govoriti → govorim. The exception is a handful of one-syllable verbs in -iti whose present ends in -jem: piti → pijem (drink), liti → lijem (pour), kriti → krijem (hide), šiti → šijem (sew); “they” is piju.
If an unfamiliar verb ends in -iti, build -im, -iš, -i, -imo, -ite, -e with confidence. Note the “they” form in -e: rade (they work), nose (they carry). It is the only form of this class without the i.
The two-way -eti: vidim, but umem
Here is the first fork. An infinitive in -eti leads into two classes, and the infinitive alone does not tell you which. One group gives -im, just like -iti; the other gives -em.

Verb classes: reading the present from the infinitive
Class: the vowel before the personal ending in the present, a, i or e (-am, -im, -em). Often readable from the end of the infinitive; for -ati and -eti not always, so learn the dictionary pair (pisati, pišem). The personal endings are shared by all classes.

Full present of each class
Class by class
- -iti → -im, almost no exceptions: radim work, govorim speak, nosim carry, kupim buy, platim pay; “they” rade, nose. Except one-syllable piti → pijem, liti → lijem; “they” piju.
- -eti: a large -im group, vidim, volim, živim, želim (“they” vide); a short -em list, umem know how, razumem understand, smem may, uspem succeed (“they” umeju, razumeju). Own stems: uzmem, počnem, donesem.
- -ati: very often -am, čitam, gledam, imam, slušam. Some soften into -em (iotation: s → š, z → ž, k → č, g → ž, t → ć, d → đ): pišem write, kažem say, plačem cry, skačem jump, glođem gnaw; “they” pišu. No clue in the infinitive: learn as pairs. Also zovem, berem (vowel change) and a few in -im: držim, ležim, trčim (“they” drže).
- -ova- → -uj-: putujem travel, kupujem buy, radujem se be glad; “they” kupuju. Only the suffix itself: pevati → pevam sing (-eva- is root). Many -ivati too: pokazujem, očekujem; but pozivam, plivam.
- -nuti → -nem: krenem set off, viknem shout; “they” krenu. Often a one-off action.
- -ći, learn as pairs: idem, dođem, nađem, izađem, but otići → odem; peći → pečem, “they” peku; moći → mogu, možeš. “They” in -u: idu, dođu, mogu.
- Loans: -irati → -am (telefoniram), -isati → -išem (funkcionišem), -ovati → -ujem (organizujem).
