Meaning
variant of Kailani, Hawaiian for 'sea and sky'
The story
Kaylani is the K-spelling of Kailani, Hawaiian elements traditionally read as sea and sky, and this batch of our worklist carries both sisters at once, which almost never happens. The record shows the pair climbing in step: Kaylani ran about 870 in the 2000s, 3,400 in the 2010s, and already 7,500 so far this decade, more than double the full 2010s with years to run. It belongs to the -lani family whose stories have filled this site tonight, Kehlani, Alani, Ailany, Leilani above them all, every spelling charted separately while the ear hears one wave. One figure is absolute: across the whole record, not one boy, 11,900 girls to zero. The K does what K always does now, marks the choice as deliberate; the sea and sky underneath do what they have always done.
