accusative singular neuter of yathārūpa (adjective/adverb)
Analysis. yathā (relative adverb "as, in the way that") + ārūpa (a- + rūpa, "form, appearance"; literally "not-form" or "formless aspect", or by reanalysis "in the form of"). The compound means "in the form/way that is fitting" or "just as it really is."
Etymology. yathā is an old relative adverb (Sanskrit yathā); rūpa ("form, shape") is cognate with English "roof" (originally a covering, hence shape) and Latin rūpes (rough rock, hence shaped stone). In the canon, yathārūpa often emphasizes perception or understanding of things in their true nature, without distortion.
