Commas Before Conjunctions
A comma goes before že, ktorý, keď, ak, aby, lebo and other words that start a dependent clause: Viem, že prídeš (I know you'll come). A plain a (and) takes no comma: čaj a káva.
How It Works
Always before a dependent clause. Words like že, keď, ak, aby, lebo, či, kým, hoci and the relative words ktorý, čo, kde start a clause that needs a comma: Viem, že prídeš. English often leaves this comma out; Slovak never does.
Clause in the middle: two commas. A dependent clause inside the main clause is closed with a second comma: Kniha, ktorú čítam, je veľmi dobrá. (see relative ktorý).
No comma before a simple a, i, alebo, ani. When these words just add one thing to another, there is no comma: čaj a káva, Otec číta a mama varí. Pôjdeme vlakom alebo autobusom.
Repeated pairs take a comma. When the joining word comes twice, as in ani ... ani, i ... i, alebo ... alebo and buď ... alebo, a comma goes before the second one: Nemám ani čas, ani peniaze. Buď príde, alebo zavolá.
Two dependent clauses joined by a. Put the comma before the first že only: Povedal, že príde a že zavolá. The same goes for ak ... a ak, aby ... a aby.
When a does take a comma.
- before a preto, a tak, a teda, a predsa, a pritom: Bolo neskoro, a preto sme išli domov.
- when a clause in the middle ends just before a: Povedal, že príde, a odišiel.
Contrast words. Ale, no, lenže and však at the start of a clause always take a comma: Chcel prísť, ale nemal čas. Však can also come later in its clause, and then the comma stays at the clause boundary: Chcel prísť, nemal však čas. (see a, ale and alebo).

Common Mistakes
Leaving out the comma before že.

Putting a comma before a simple a.

Forgetting the second comma after a clause in the middle.
Muž, ktorý tam stojí je môj učiteľ.Muž, ktorý tam stojí, je môj učiteľ.A clause inside the sentence needs a comma at its end too, before the main clause continues.
