Related to the Latin word for light.
The Latin name entry explicitly relates Lucius to lux, light, through older Latin and Italic forms. This is a root relationship, not a statement that Lucius is simply a spelling of Luke or that every bearer was born at dawn.
Latin Roman personal name, later borrowed into English.
The Latin section identifies the Roman praenomen, while the exact English etymology describes borrowing from Latin. This replaces a language-of-use label with the documented historical route.
/ˈluːsɪəs/; /ˈluːʃəs/
The exact English personal-name entry records these UK alternatives, approximately LOO-see-us and LOO-shus. The fuller and compressed readings remain separate; Latin pronunciation is not substituted for English.
Recorded English reading, as published. Accents and preferred pronunciations can differ.
Counts apply only to the exact spelling, place, year and recorded usage shown. Places are separate; these figures are never added into a worldwide total. Missing or suppressed records never mean zero.
| Place | Year | Recorded usage | Published births | Rank | Notes |
|---|---|---|---|---|---|
| Canada | 2025 | Boys | 20 · preliminary | 1207 | 2025 figures are preliminary. Quebec counts below five are randomly imputed by the publisher before national aggregation. Accents are removed in the source; this profile was matched only where the catalog spelling was unambiguous. Unpublished values are unknown, not zero. Rank basis: source published. |
| France | 2025 | Boys | 5 (rounded to 5) | 4604 | Counts are rounded to the nearest multiple of five. Ranks use unrounded publisher counts with randomly ordered ties; equally rounded counts can have different ranks. National coverage excludes Mayotte before 2012. Missing years are unavailable, not zero. Automated direction labels are withheld for this rounded-count series. Rank basis: source published. |
| England & Wales | 2025 | Boys | 26 | 1124 | Source-reported counts; unpublished names are not zero. Rank basis: source published. |
| United States | 2025 | Boys | 189 | 1128 | Source-reported counts; unpublished names are not zero. Rank basis: calculated from published counts. |
Canada, Ireland and France coverage includes confidently matched existing profiles only; unmatched spellings are awaiting review. French counts are rounded to five.
