przybysku

Przybysku is a Polish form associated with the noun przybysz, meaning "newcomer", "arrival" or "stranger". It appears chiefly as an address — a vocative or colloquial variation used when speaking directly to someone who has recently arrived or is perceived as an outsider. The form carries informal, sometimes affectionate or ironic connotations depending on context.

Etymology traces back to the verb przybyć ("to arrive") with the agentive suffix that produced przybysz. Przybysku itself is not the standard literary vocative (which is usually przybyszu) but occurs in regional speech, dialects, folklore and modern colloquial usage. Writers and speakers may choose przybysku for rhythm, emphasis or stylistic color.

Typical contexts include everyday greetings, storytelling and dialogues in literature where an arrival or outsider is being addressed: for example, "Cóż robisz tutaj, przybysku?" The word can convey welcome, suspicion or teasing tone depending on intonation and surrounding words.

Related forms are the nominative przybysz, genitive przybysza and other regular declensions. Przybysku should be understood as a pragmatic variant rather than a separate lexical item; usage frequency and acceptability vary by region and register.
