Lilian
Meaning
variant of Lillian (probably a diminutive of Elizabeth, or an elaborated Lily); a Brazilian classic of the 1970s and 80s, one l lighter than the original
The story
Lilian is Lillian traveling one letter lighter, and Behind the Name adds a twist most readers miss: in French and Romanian it is a masculine name, ranked 468th for French boys in 2024. The name underneath comes with the source's own honest shrug: Lillian was probably originally a diminutive of Elizabeth, or may be an elaborated form of Lily, from Latin lilium, and Behind the Name commits to neither. What is certain is the record. American girls named Lilian appear in every decade since the 1890s, with an early-century run that reached 637 in the 1910s and a modern wave that hit 5,935 across the 2010s, 3,046 so far in this one. And Brazil is where the single l became a signature: the census counts 107,581 residents, 40,075 of them from the 1980s alone, the exact decades this page's own meaning card names. One letter lighter, and on two continents, entirely its own.
