Da, ker, če, ko: two thoughts in one sentence

Until now you spoke in short sentences. Four conjunctions turn them into connected speech: da — that, ker — because, če — if, ko — when. The set covers almost everything a person narrates about their life. For example: “Vem, da ti bom pomagal, ker si moj brat” — I know I'll help you, because you're my brother. A rule from the Slovenian course: worked out on examples, not memorized as a wording.

How it works

Until now you spoke in short sentences. Four conjunctions turn them into connected speech: da — that, ker — because, če — if, ko — when. The set covers almost everything a person narrates about their life.

The first thing to know about a subordinate clause: it does not shove the verb to the end. Learners of German get this as the main gift of Slovenian: the verb stands where it would in a standalone sentence, nothing at the end of the clause. Vem, da prideš jutri — I know you're coming tomorrow. Second: the comma before the conjunction is always obligatory, no exceptions and no leniency for short clauses: Grem domov, ker sem utrujen.

What the clause does shift are the little unstressed words. The conjunction takes first place, and the clitic lands immediately after it: Vem, da ti bom pomagal, Ker se mi mudi, grem, Če se ne motim, je zaprto. Parking the pronoun further away is the most audible foreigner's mistake — louder than any case ending.

Three fine points people trip on. Ko is 'when' for a one-off event, kadar is 'whenever': Ko sem prišel domov, sem zaspal versus Kadar dežuje, ostanem doma. In a future time clause Slovenian keeps the future, where English drops 'will': Ko bom prišel, te pokličem — literally 'when I will come, I'll call you'. And don't confuse ker with zato: ker answers 'why' and introduces the cause, zato is 'therefore' and introduces the consequence. Zakaj? Ker ni signala.Ni signala, zato ne morem klicati.

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.
