Czech to European Portuguese: who performs the intended action?
Identify the intended actor before translating a purpose clause
Czech can express purpose with aby and a finite verb, or with an infinitive in an appropriate construction. CzechEncy contrasts someone going to return bottles with someone sending another person to return them. In the second construction, the person sent performs the returning; the sender need not accompany them.
This matters when translating into Portuguese for Portugal because a short infinitive phrase must still identify the correct actor. Do not treat a Czech sentence containing an infinitive as proof that the subject of the main verb performs every action. Determine who goes, who sends and who completes the intended task.
Czech aby forms can also make person explicit. An ending identifying us should not disappear into a Portuguese phrase whose actor could be somebody else. Preserve the participant relationship first, then choose the target clause type; reproducing the visible Czech number of words is not a reliable way to preserve that relationship.
Portuguese infinitives can themselves distinguish participants
Priberam’s Portuguese conjugation of fazer lists personal-infinitive forms including fazeres for tu, fazermos for nós and fazerem for eles, elas or vocês. Czech infinitives do not carry an equivalent personal paradigm. The similarity of the grammatical label infinitive therefore conceals an important difference in what the form can specify.
Ciberdúvidas illustrates this with para fazeres and para fazermos: the endings identify the person without requiring an additional pronoun in those examples. By contrast, para eu fazer makes the first-person singular actor explicit. Fazer alone does not distinguish that person from third-person singular in the paradigm.
For a Czech instruction assigning work to us, the Portuguese wording must retain that assignment. A phrase meaning for us to do and one merely describing work to be done are not interchangeable. Removing a participant because the target phrase looks shorter can turn an allocation of responsibility into an unspecified task.
An intended outcome is not a completed outcome
The Czech purpose reference characterizes the result of an aby clause as intended or wanted. Sending a person to obtain something does not itself assert that the person succeeded. The Portuguese translation must retain that distinction between the purpose of an action and a later report of its achievement.
Personal-infinitive endings are person and number information, not evidence that the action occurred. A form identifying us does not establish completion, just as a Czech purpose clause referring to us does not guarantee success. Time and event status must come from the larger construction and context.
When translating a Czech account of an errand, keep its two layers separate: the actual sending or going, and the intended subsequent action. This prevents a target sentence from reporting a finished purchase where the source only stated why someone left. The useful comparison is between participant control and intended outcome, rather than between isolated verb endings.
