Present Tense: -e- Verbs and Stem Changes

The -e- conjugation is the third and most demanding of the regular present classes. Its endings are perfectly regular — -em, -eš, -e, -emo, -ete, -u — but the stem is where the action is. This is the class where the infinitive most flagrantly lies to you: pisati ("to write") gives pišem, not pisam; putovati ("to travel") gives putujem, not putovam; brati ("to pick") gives berem, not bram. None of these is truly irregular. Each follows a predictable sub-pattern, and once you learn the three or four sub-rules below, the apparent chaos of the e-class becomes a small set of tidy transformations.

The endings

The 3rd person plural ending is -u (pišu, putuju, beru) — different from the -i- class, whose "they" form is -e (oni rade). This -u vs -e split is the single most reliable way to tell the two classes apart in the wild.

Sub-pattern 1: simple stems (no surprise)

Many e-class verbs add the endings to a clean stem with no alternation. These are the easy members — learn them and relax.

The -nuti verbs (krenuti, dignuti, kliznuti) and the short monosyllables (piti → pijem, čuti → čujem, piti takes a -j- glide to break the vowel hiatus) sit here. Note piti → pijem and čuti → čujem: a -j- appears so two vowels do not collide.

Sub-pattern 2: jotation (the consonant changes)

A large set of verbs whose infinitive ends in -ati undergo jotation in the present: the final stem consonant softens before the present-tense vowel. This is the same sound change you meet in comparatives (jak → jači) and noun formation — not a quirk of verbs, but a deep regularity of the language. The classic alternations:

The pattern is consistent: whatever consonant sits at the end of the stem shifts to its "soft" partner. If you have already met visok → viši or Bog → Bože, you have already met this change. So pisati → pišem is not an irregular verb to be feared — it is jotation, plainly applied.

Sub-pattern 3: -ova- / -eva- / -iva- → -uje-

Verbs whose infinitive ends in -ovati, -evati or -ivati swap that whole chunk for -uje- in the present. This is the most productive sub-pattern of all — it is how Croatian conjugates nearly every borrowed and newly-coined verb (organizirati aside), so it is worth automating.

Sub-pattern 4: vowel-mutating stems

A small but very common set changes the vowel of the stem, not a consonant. The infinitive shows one vowel and the present shows another (or inserts one where the infinitive had none). These you simply learn, but they cluster, so they reward a little memorisation.

Why the infinitive betrays you here

In the -a- and -i- classes the infinitive mostly predicts the present. In the e-class it frequently does not, because the e-class collects the archaic and athematic stems of the language — the verbs whose present stem and infinitive stem genuinely differ. Pisati and pišem descend from the same root through two different stem-forming suffixes; the -ova-/-uje- swap is a fossilised alternation; the vowel changes in brati/berem preserve an old vowel pattern that the infinitive levelled and the present kept. You are not memorising random forms — you are memorising the present stem as a second principal part. Store pisati → pišem, putovati → putujem, brati → berem, and the rest of each paradigm falls out mechanically.

Common Mistakes

Key Takeaways

• Endings: -em, -eš, -e, -emo, -ete, -u; the 3pl -u is the giveaway distinguishing this class from the i-class -e.
• Four sub-patterns tame almost everything: simple stems, jotation (pisati → pišem), -ova-/-eva- → -uje- (putovati → putujem), and vowel-mutating stems (brati → berem).
• Treat the present stem as a separate principal part — learn infinitive → 1sg present together for every e-class verb.
