The story
Teo has a busy school book: math, a telling-off, a museum visit, even Little Red Riding Hood performed by puppets. In Teo en la escuela, a book of lessons and excursions, the ordinary business of being a child supplies plenty of adventure. The picture books appear under Violeta Denou, a shared pen name whose illustrators include Carlota Goyta and Asunción Esteban. The small name on the cover has several routes of its own. Teo can shorten Teodoro and other names beginning that way, while Georgian Teo is a feminine short form of Teona. Three letters need not point back to one full name. In the books, though, they are enough to introduce a child whose world has room for lessons, trouble and a puppet show.

share of the boys on the register for that year, SSB’s own figure
People who have or have had a Norwegian ID number, emigrants left out, from Statistics Norway’s name statistics (release of January 2026): by year of birth for 1945–2020 (everyone born that year who was ever registered in Norway, including people who registered later and people who have since died) and by year of naming from 2021; only first names carried by 200 or more living people are listed, counts under 4 are withheld, and SSB merges spellings that differ only by letters outside the Norwegian alphabet. The shares are SSB’s own, of the people of that sex and year in that count; the 2025 figure counts the children named that year, and no year is a count of births.
