Verbs of completion and addition (do-)

The prefix do- for addition

The aspectual prefix do- often marks adding to an existing quantity. For example, adding it to the verb for "to write" creates dopisać (to append):

We must append this clause to the contract.
Musimy dopisać tę klauzulę do umowy.
It is important to me to add a new paragraph.
Zależy mi na tym, żeby dopisać nowy paragraf.

It also applies to paying an additional amount (dopłacić):

If the client signs the annex, he will have to pay extra.
Jeśli klient podpisze aneks, będzie musiał dopłacić.

The prefix do- for completion

The prefix do- can also indicate that an action has been brought to its final conclusion. For instance, doczytać means to read something to the very end:

This provision is long and unfortunately I didn't read it to the end.
Ten zapis jest długi i niestety go nie doczytałem.

In legal drafting, finalizing exact details is crucial. Doprecyzować means to clarify or pin down precise terms:

When will you clarify the conditions of the contractual penalty?
Kiedy doprecyzują państwo warunki kary umownej?

Similarly, dopracować means to refine or work on a document until it is perfectly finished:

It is important to the boss to refine this annex.
Szefowi zależy na tym, żeby dopracować ten aneks.
