Apologies to those who cannot read Unicode, but, indeed, τὸ <https://en.wiktionary.org/wiki/%CF%84%E1%BD%B8#Ancient_Greek> *γρᾰ́μμᾰ* is neuter. All the -ma nouns that are derived from verbal stems are neuter, and take -ta as the plural suffix. Apparently the original Indoeuropean suffix (something like -mn-) was also neuter, and since we can't reconstruct further back, there isn't any way to say why.

Why not start at the north pole, go south to equator, east on equator for 90 degrees, then north back to north pole. What am I missing??

(__agramma is neuter?) I just learned of this. Choose a point on a 2-sphere and traverse 90º of a great circle. Hang a 90º left turn. Traverse another 90º arc. Turn. Iterate. When, if ever, do you return to your starting point? —rwg _______________________________________________ math-fun mailing list math-fun@mailman.xmission.com https://mailman.xmission.com/cgi-bin/mailman/listinfo/math-fun
