Or even pedagogical :) I wrote "hermeneutical" -- similar idea, different
word. Also, you may be uncomfortable with the term "folk etymology" but
that seems to be the standard term for non-philological etymologies.

> Would you want etymologies like dhamma = "the duty of one's social class"?
That is a definition, valid in some contexts, not an etymology. An etymology
would give the verbal root DH.R and its presumed meaning.

Best wishes,
