I thought "i" and "ma" were interchangeable. Does it really matter which one is used in this sentence? Doesnʻt both words mean, "in, on, or at"?
But in this sentence, "i" is an object marker, so it canʻt be changed. The lumi kuke is what he is cleaning, not where he's cleaning.
can "i nā manawa a pau" mean generally the same thing as "mau" here ("always"?)
