8. Naming.
When children have, by repeated sensations, got ideas fixed in their memories, they begin by degrees
to learn the use of signs. And when they have got the skill to apply the organs of speech to the framing of
articulate sounds, they begin to make use of words, to signify their ideas to others. These verbal signs they
sometimes borrow from others, and sometimes make themselves, as one may observe among the new and unusual
names children often give to things in the first use of language.
