Speachsteadlore is the lore about the sweys in speech that can make words unalike from each other. It is a field of speechlore. These speech-bits or speechlings make up words and the greater bits of speech.
Some spots in the mouth have been given names so that we can talk about them. Breath can be shaped in the mouth by the tongue, lips and teeth to form many unalike sweys:
These spots are as follows, from the fore of the mouth to the back:
lips: a bit of speech made from the lips (Eng. labial)
Some speech-bits are made with both lips (bilabial)
lip-tooth: a bit of speech made between the lower lips and upper teeth (labiodental)
teeth: a bit of speech made with the tongue against the teeth (dental)
behind-teeth: a bit of speech made with the tongue against the spot right behind the teeth (alveolar)
roof: a bit of speech made with the tongue against the roof of the mouth (palatal)
Another way the sweys of speech can be unalikened is by how they are spoken: whispered or with steven. The sweys spoken with steven (voiced) can be felt by the quaking of the throat-folds when they are spoken. The whispered sweys lack this quaking and are made only by the shaping of breath in the mouth.
