Fialov

Fialov is a Slavic surname, typically masculine, that appears in contexts influenced by Czech and other Central European naming traditions. It is formed from the Czech adjective fialový, meaning violet or purple, with the common Slavic surname suffix -ov. The combination is generally interpreted as a toponymic or nicknames-based family name reflecting color-related association.

In Czech, the feminine form of the surname is Fialová, following standard gender inflection for adjectives used as surnames. When diacritics are omitted in non-Czech contexts, Fialová may appear as Fialova, while the masculine form without diacritics appears as Fialov. The diacritic-less form is common in international records and genealogical sources that adapt Czech spellings.

Geographically, the name is most often encountered among Czech-speaking populations and communities with Czech heritage. It can also be found in diaspora communities in other parts of Europe and North America, where Czech surnames were carried through migration and adaptation.

Variants and related spellings arise from transliteration practices and historical changes in orthography, but Fialov remains the standard masculine form in non-diacritic records. The surname does not imply a specific occupation or lineage beyond its color-based origin; as with many color-derived surnames, it may reflect a characteristic associated with an ancestor rather than a direct profession.
