"The spoon is in the bedroom."

Translation: Aia ke puna ma ka lumi moe.

[BarbaraLea954887]

Any information on why "Puna" takes "ke" instead of "ka"?

[rabelon]

Spoon is preceded by “ke” because it is an irregularity to the article rule, similar to table, “ke pākaukau.”

[DABurnside]

Would that also be true for ʻō/fork?

[Komota15]

I do believe it is, yes.
