What does machteva mean in Hebrew?

Answer 1

It depends on how you spell it in Hebrew:

מַחֲלָה = "sickness"

מָחְלַה = "she forgave"

There might be others as well, but that's all that comes to mind.

Answer 2

machteva doesn't appear to mean anything. Perhaps you meant michtavah (מִכְתָּבָה) which means "writing desk."
