I would pronounce it like the word ear but with a hard k sound in front and an ‘uh’ sound a the end. Two syllables, stress on the first syllable.
I would definitely say it to rhyme with ‘mirror’
Kee-Ruh or KeeR-uh
As others have said I would pronounce it Kee-ra or Keer-ah with the ee sounding like Key
I had seen your other post and I think my confusion is that I pronounce mirror as meer-ror (slightly different then Key) which would make think that it should be pronounced Keer-ror to rhyme
