Polish words that need a second look in a Czech message
A familiar building name can send someone downstairs
Polish sklep normally identifies a shop. Czech sklep ordinarily identifies a cellar, although historical and specialized uses exist. For a present-day shopping message, “Idę do sklepu” should therefore be “Jdu do obchodu.” Keeping the apparent cognate would change the destination. This is an especially useful check when translating pickup instructions or telling somebody where you have gone.
Distinguish a business name from the ordinary noun around it. If a Polish store has an official name, preserve that name while translating the description of the location. Do not turn a proper name into a cellar simply because it contains a familiar-looking word. Establish whether the text identifies a particular business, describes a building space, or gives a general destination.
Fresh bread needs the Czech word that means fresh
For bread, Polish czerstwy means that it has become dry and hard with age. Czech čerstvý, despite its similarity, can mean fresh. “Kupiłem świeży chleb” can become “Koupil jsem čerstvý chléb.” Translating Polish świeży with the Czech word is correct here, while preserving Polish czerstwy by spelling resemblance would reverse the food description.
Treat this as a contrast in the relevant sense, not a claim that either adjective has only one meaning in every context. In particular, descriptions of a person may use different dictionary senses. A food order or a complaint about a loaf needs the condition of that food, rather than an automatic substitution based on the first adjective listed in a bilingual search.
Confirm the month before confirming the appointment
Polish kwiecień is April, whereas Czech květen is May. Their resemblance is therefore unsafe in a date. “W kwietniu” becomes “v dubnu.” An appointment moved into Czech květen would have shifted a whole month, even if every other part of the message were fluent.
When a source contains both a written month and a numeric date, check that they agree before translating either one. If they conflict, do not silently invent the intended date. A translated invitation should retain the actual day, month, and year. Write the Czech month in the grammatical form required by the phrase rather than treating the dictionary headword as a universal date form.
Polite Polish address becomes a Czech relationship, not a copied title
Polish pan and pani commonly form courteous address with third-person verbs. Czech normally uses vy and the associated second-person plural verb forms for polite address to an individual. Retain the courtesy without copying the Polish construction word for word. A Czech sentence that accidentally talks about a third person can otherwise replace a direct request to the recipient.
The two languages share many recognizable roots and grammatical categories, but those similarities are not permission to transfer whole constructions unchecked. For a practical message, the most valuable final pass is concrete: is the destination a shop, is the food fresh, is the month correct, and is the same person being addressed? These are small differences with immediate consequences for the reader.
