The story of Keelin
Lenition is the machinery that makes written Irish look impenetrable to outsiders, and it is a genuinely elegant system. Irish consonants change at the start of a word depending on grammar — after certain words, in certain constructions — and rather than spell the changed sound differently, Irish writes the original consonant and adds an h to show what has happened to it. The reader is being told two things at once: what the word is, and what has been done to it. English has nothing comparable, and the price is that half the letters in an Irish name are instructions rather than sounds.
Meaning
slender and fair
The Irish name is built from two words, one meaning slender and one meaning fair or white. In the original spelling the second element begins with an f that is lenited — softened — and Irish shows this by adding an h, which silences it completely. So the name is said as though the f were not there, and an English reader looking at the Irish spelling has no way of knowing that. This is why the anglicized forms look so unlike the originals.
How the name formed
- two Irish words meaning slender and fair
- lenition silences the second element's first letter

Two syllables, stress at the front. The Irish original is said the same way despite looking twice as long, which is the point.

Fashion outlook
Keelin 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.
