accusative singular masculine
Analysis. saṁ (together) + ā (toward, up to) + √dhā (to place, to hold) = 'placing together, bringing into one'. The spatial sense of gathering and unifying becomes the psychological state of mental unification.
Etymology. The root √dhā (place, hold) is cognate with Sanskrit dhā and English do, dough (things placed, formed). The prefix saṁ (together, like Latin con-) works with ā (toward the speaker) to express the reversal and gathering of mental faculties into a single point of focus.
