Reading a Czech message as an English reader needs it
Do not mistake an unstated subject for a missing person
Czech often leaves out a subject pronoun when the verb and the conversation identify who is speaking. “Přijedu zítra” can be “I’ll arrive tomorrow.” English needs the I for an ordinary complete statement even though Czech já is absent. The ending supplies information that the English sentence has to express separately.
This becomes more important in a sequence of messages with different speakers. Track who wrote each sentence and who is being discussed before you replace an omitted pronoun. A polished English update can still be wrong if an action performed by the customer is assigned to the writer. Do not let the person named first in the exchange become the automatic subject of every later sentence.
Read the event before choosing an English tense
“Psal jsem e-mail” can mean “I was writing an email.” “Napsal jsem e-mail” can mean “I wrote an email,” with the completed result in view. The distinction comes from Czech aspect as well as tense. Natural English may need a different construction to bring out the same difference.
These examples are contextual alternatives, not a universal rule that psal always requires was writing or napsal always requires wrote. A sentence about what someone did repeatedly, or an update about something just completed, may call for different English wording. In work messages, ask whether the text establishes a finished result or describes the activity. That distinction affects the practical meaning more than preserving the original number of verbs.
A polite plural form need not mean several people
Můžete can address a group, but it can also address one person politely. An English translation should not automatically add all of you or otherwise turn a singular customer into multiple recipients. Check the salutation, the recipient, and the wider exchange. The English you can carry either meaning without making the distinction explicit.
Courtesy can then be retained through the wording of the request. A Czech polite question need not become an English sentence talking about the recipient in the third person. Equally, familiar Czech wording should not be inflated into a ceremonial letter. Preserve the relationship the message actually establishes.
Recognize the same person behind different name forms
Czech names can change form when directly addressing someone or when their grammatical role changes. A changed ending does not necessarily identify a second person. Before creating separate English references, work out whether the forms belong to the same name. This is useful in email openings, appointment reminders, and instructions about handing a document to somebody.
English usually uses the established name without reproducing Czech case endings. Where the official spelling is available, keep it for identification and preserve its diacritics. Do not reverse-engineer an unfamiliar name with confidence from a single inflected form; refer back to the signature or other reliable context. Correct participants and a readable English sentence are more useful than an invented spelling that merely looks plausible.
Language references
Czech uses case endings and diacritics to distinguish words. Preserve accents in source text. Check formal vy versus informal ty and verify the inflection of personal names.
English words such as “bank” and “right” have several meanings. Add a full sentence to help resolve them. English “you” does not distinguish formal address or singular from plural; specify the audience when reviewing the result.
