Aspect: delati or narediti, and why the border is not where you expect
Aspect in Slovenian is close to what English does with 'was writing' and 'have written': one shape looks at the process, the other at the finished fact — except that here it is a property of the verb, not of the tense. Most verbs come in pairs: imperfective delati and perfective narediti, pisati and napisati, kupovati and kupiti. Pairs are built three ways: a prefix (pisati → napisati), a suffix swap (kupiti →…
How it works
Aspect in Slovenian is close to what English does with 'was writing' and 'have written': one shape looks at the process, the other at the finished fact — except that here it is a property of the verb, not of the tense. Most verbs come in pairs: imperfective delati and perfective narediti, pisati and napisati, kupovati and kupiti. Pairs are built three ways: a prefix (pisati → napisati), a suffix swap (kupiti → kupovati) and rarely a different root (vzeti → jemati).
The first divergence — the future tense. Slovenian has one future for both aspects: bom delal and bom naredil. The formula is the same, only the participle changes, and there is no 'simple future' for the perfective.
The second — the present of a perfective. Naredim exists, but it is not a present: it means either the future in a time clause (Ko naredim, ti povem — when it's done, I'll tell you) or a repeated single action (Vsak dan napišem eno stran — every day I write one page).
The third, and here you must pay attention, is aspect after modal verbs. Moram napisati pismo — I have to write the letter, once, through to the end. Moram pisati pismo — I'm supposed to be writing, to be at it. Slovenian picks the perfective noticeably more often than English would: moram vprašati, moram poklicati, moram plačati. Under negation it flips: Ni treba plačevati sounds more natural than ni treba plačati.
And the fourth — biaspectual verbs, more numerous than an English speaker expects. Every borrowing in -irati has no aspect pair at all: rezervirati, blokirati, kopirati, telefonirati. Rezerviram sobo means both 'I reserve' and 'I'll have reserved'. Do not invent zarezervirati — reaching for that nonexistent prefix is the most typical mistake.
Table
| imperfective | perfective | where the difference is heard |
|---|---|---|
| delati | narediti | delal sem / naredil sem |
| pisati | napisati | pisal sem uro / napisal sem pismo |
| kupovati | kupiti | kupujem vsak teden / kupim danes |
| plačevati | plačati | ni treba plačevati / moram plačati |
| jemati | vzeti | jemljem zdravila / vzamem tableto |
| the future | one for both | bom delal / bom naredil |
| the perfective 'present' | not a present | ko naredim, ti povem |
| -irati verbs | no aspect pair | rezerviram = I reserve and I will reserve |

How the rule settles in your head
A rule is not memorized from an explanation. It is memorized from an attempt to use it and a mistake — that is why the app delivers it mixed in with words, not as a separate lesson: it resurfaces exactly where you forgot it.
