0 — No Polish boy names start with V. Rely on Polish civil registries (PESEL/birth records) and standard Polish name dictionaries as authoritative sources: they show no native male given names beginning with the letter V. Note that Polish orthography uses the letter W to represent the /v/ sound, so names that appear to start with V in English almost always have Polish forms beginning with W (for example Wiktor or Wojciech).

Understand why the criterion returns no results. The letter V is not native to Polish spelling and appears mainly in loanwords or foreign-name spellings; official name lists prioritize names attested in Polish usage, so inventing or importing V-initial forms would break that rule. Consider close fits instead: Polishized equivalents (Wiktor for Victor/Viktor), occasional immigrant or international spellings that use V but remain rare, or searching for Polish names that produce the /v/ sound (W‑names) when you need authentic, well-documented options.
