Narrow, strait, or church
Kilah is most often considered a variant of the Irish name Keila or Sheila, or a shortened form of the Hebrew name Shakila. In an Irish context, it relates to 'caol', meaning narrow or slender, or 'cill', referring to a church or cell. It is a rare, modern choice that offers a unique phonetic profile while remaining easy to pronounce.
