subtonic

The elementary sounds of speech are of three natural divisions; the tonics, the subtonics, and the atonics.

"So gradually as to allow its being engrafted on a subtonic."

Indefinite Syllables are capable of almost indefinite prolongation; they are those which terminate in a tonic, or any subtonic except one of the three abrupt subtonics, b, d, g; for example, awe, fudge, hail, arm.

Be careful not to convert the subtonic into a tonic.

Proceed in a similar manner with the other subtonics.
