Making Czech choices that an English sentence does not reveal
An English past-tense sentence may need two Czech versions
“I was at home” can be “Byl jsem doma” for a speaker using masculine agreement, or “Byla jsem doma” with feminine agreement. English was does not tell the translator which form to use. This is not a stylistic preference between two equivalent spellings: the Czech participle reflects the speaker’s agreement. A translation written for someone else must therefore take its sender into account.
The same issue occurs when reporting what another person did. Use information established in the message rather than guessing from a profession, hobby, or name whose reference is uncertain. If the sender is an organization, a suitable collective or impersonal formulation may be clearer than inventing an individual speaker. First establish who owns the statement, then check its Czech forms.
Keep familiar and polite requests separate
Czech ty addresses one person familiarly; vy can address several people or one person politely. The verb reflects this distinction even if the pronoun is not written. “Can you wait?” can be “Můžeš počkat?” to a familiar individual, whereas “Můžete počkat?” suits polite address or a plural audience. English does not visibly distinguish these situations.
A customer email should not change between those forms without a reason. If several sentences all address the same person, inspect their verbs together. Merely adding a polite greeting will not repair familiar verb endings in the rest of the text. Conversely, a friendly personal message need not acquire distant wording just because the translation uses complete, carefully written sentences.
A task in progress differs from a finished result
Czech psát and napsat illustrate the distinction between imperfective and perfective aspect. Both can concern writing, but they present an event differently. When an English update says that someone was writing an email, it need not imply that the email was finished. A completion notice requires the completed-result reading instead. Choosing the wrong member of the pair can change what a colleague believes is ready.
An English simple past is not automatically a command to use a perfective Czech verb. Repeated activities and descriptions of a process need their own reading. Look for what the writer is asserting about the event: completion, duration, habit, an attempt, or a planned outcome. Do not form a supposed counterpart by attaching a random prefix; Czech verb pairs and their meanings need lexical checking.
Preserve the Czech spelling that carries these distinctions
Czech marks vowel length and uses letters such as č, š, ř, and ž. Those marks belong to the word. Removing them from an edited message is not the same as choosing a simpler style. Keep the spelling of the translated verbs and names intact, especially if a reader will use the text to search for an address or identify a person.
Before sending, review the sender, the recipient relationship, and the status of the task together. These are precisely the details that a short English sentence can leave implicit while Czech grammar asks the writer to make them visible.
Language references
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.
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.
