sañcopati

to move, to stir; a misunderstood term. Found in aor. samacopi (so read for T. samadhosi & variant reading samañcopi) mañcake “he stirred fr. his bed” SN.iii.120, SN.iii.125; and sañcopa (pret.) Ja.v.340 (variant reading for T. sañcesuṃ āsanā; C. explains as “caliṃsu”).

cp. Sk. copati, as α ̔́πας in Mhbh. We should expect copeti in Pāli, fr. cup to stir
