Kasi
Feminine
Kasi is overwhelmingly a girls’ name — 2,280 girls against 61 boys since 1880.
Kasi is Casey with two separate respelling habits applied at the same time. The C has become a K, which is one convention, and the -ey has become a single i, which is another. Either change alone would leave the name recognizable; both together produce something that has to be sounded out.

The story of Kasi
The same four letters are a place of some importance on the other side of the world. Kashi is the older name of the city on the Ganges now usually called Varanasi, and it is among the oldest continuously inhabited cities anywhere. The name is generally glossed as the shining or luminous one, and the city has been a destination for pilgrims for longer than most countries have existed. There is no reason to think an American family reached the spelling that way rather than through Casey, and every reason to think most did not. But a name is not only what its parents meant by it, and a reader who meets these letters somewhere else will not be wrong to recognize them.
Meaningnot established
Not established
If the source is Casey, the sense runs back to an Irish surname whose own meaning is disputed. If the source is elsewhere, it is not recoverable from the record. The spelling is too short and too new here to settle the question either way.

Pronouncing Kasi
KAY-see
Two syllables with the stress at the front, said as Casey is said. The final i invites some readers to try KAH-see instead, and the spelling does not rule it out.

Fashion outlook
Kasi sits outside the current charts, and that is its own kind of answer: naming cycles can only date the names they carried up. A name this rare has no decade stamped on it — it cannot go out of fashion, because it was never in.

The trade-off
- It is short, unisex and completely easy to say once the reading is fixed.
- The spelling is distinctive without containing anything difficult.
- It is extremely rare, so the child will not share it with anyone nearby.
- Two respellings at once means strangers will hesitate before saying it.
- There is no established meaning to offer and nothing older behind it.
- The record holds girls as well, and the girl is the smaller side of a very small name.
Nobody names a baby alone.
