A word for “potter” in The Etymologies of the 1930s under the root ᴹ√KEM “soil, earth”, apparently an agental formation based on ᴹQ. kemna “of earth, earthen” (Ety/KEM). It was first written as ᴹQ. {kemenāro}, and there was a line drawn from kemnaro to forms ᴹQ. kentano and N. cennan in the margin, but both these marginal forms were deleted (EtyAC/KEM).
