What must stay explicit when Slovenian becomes Slovak
Preserve two-person information when the dual disappears
Slovenian dual forms can identify exactly two participants without a separate numeral. Slovak normally uses plural forms instead, so that information may need to be expressed in words. “Midva prideva jutri” can become “My dvaja prídeme zajtra.” The translated message still says that the two people, rather than an unspecified larger group, will arrive tomorrow.
You do not need to write dvaja in every sentence if a two-person booking is already clear. Keep it where a recipient needs the information, especially in an isolated arrival message or a request for transport. A plain Slovak plural is grammatically normal, but it does not by itself reveal the same exact group size.
Also identify whether a dual form counts the speakers, the people addressed, or the objects being discussed. Two guests can reserve several rooms; several guests can reserve two rooms. Do not collapse those facts into one count. The useful translation preserves the number attached to each participant group and item, rather than trying to reproduce a Slovenian ending.
Slovensko in a language expression is not a shortcut to Slovak
“Govorim slovensko” means that the speaker speaks Slovenian. In Slovak, a suitable rendering is “Hovorím po slovinsky.” Using po slovensky would change the claim to speaking Slovak. Similar-looking language labels are therefore a practical false friend in this direction, even when the rest of the sentence seems straightforward.
Slovenian slovenščina corresponds to Slovak slovinčina, while Slovenian slovaščina corresponds to Slovak slovenčina. Keep those names distinct in requests for an interpreter, school records, and descriptions of a document. The source language of a text is not automatically the same as the nationality of the person sending it.
The destination deserves a separate check in travel correspondence. Slovenia and Slovakia are different countries despite the similar language names. If a message includes a city, an address, or an official organization name, retain the established identity. Do not “correct” a valid destination simply because its spelling looks less familiar than the neighboring country’s name.
A tiny change in a familiar verb can still be required
“Sem doma” can become “Som doma,” meaning “I am at home.” The close resemblance makes the sentence easy to recognize, but keeping the Slovenian sem would not produce the normal Slovak form. Treat recognition as the starting point for translation, not proof that the sentence already belongs to the target language.
Follow the same principle with reflexive words, prepositions, and case endings. A Slovak phrase may need its own form even where a Slovenian root is readily understandable. Preserve who is speaking and where they are, then rebuild the sentence with Slovak grammar. This matters most in short messages: a language label, a group-size ending, or a small verb form can carry much of the information the reader needs. Check those details before polishing longer, more recognizable words.
