shape and voice, commonly make the whole nominal essence.

Names of mixed Modes stand alway for their real Essences, which are the workmanship of our minds.
Another thing we may observe from what has been said is, That the names of mixed modes always signify (when they have any determined signification) the REAL essences of their species.

For, these abstract ideas being the workmanship of the mind, and not referred to the real existence of things, there is no supposition of anything more signified by that name, but barely that complex idea the mind itself has formed; which is all it would have expressed by it; and is that on which all the properties of the species depend, and from which alone they all flow: and so in these the real and nominal essence is the same; which, of what concernment it is to the certain knowledge of general truth, we shall see hereafter.

Why their Names are usually got before their Ideas.
This also may show us the reason why for the most part the names of mixed modes are got before the ideas they stand for are perfectly known.
Because there being no species of these ordinarily taken notice of but what have names, and those species, or rather their essences, being abstract complex ideas, made arbitrarily by the mind, it is convenient, if not necessary, to know the names, before one endeavour to frame these complex ideas: unless a man will fill his head with a company of abstract complex ideas, which, others having no names for, he has nothing to do with, but to lay by and forget again.

I confess that, in the beginning of languages, it was necessary to have the idea before one gave it the name: and so it is still, where, making a new complex idea, one also, by giving it a new name, makes a new word.
