пък
The Bulgarian word "пък" is a conjunction meaning "however," "but," or "on the other hand."
In this case, "пък" emphasizes the speaker's contrasting opinion in a discussion or argument.
Аз пък смятам, че трябва да опитаме пак.
I, however, think that we should try again.
In this sentence, "пък" is used to contrast two situations: being busy today and having time tomorrow.
Той е зает днес, пък утре ще има време.
He is busy today, but tomorrow he will have time.
Here, "пък" introduces a surprising turn of events concerning the completion of one action but the oversight in another.
