Examples
“Copula This couples (hence the Latinate term copula) the individual probabilities associated with A and B to come up with a single number.”
Wired: Recipe for Disaster: The Formula That Killed Wall Street
“It is often an awkward task so to analyse propositions relative to past or future time as to bring out the copula under the form 'is' or 'is not': but fortunately there is no necessity for so doing, since, as has been said before (§ 188), the material form of the copula is a matter of indifference to logic.”
“The Verb, as such, is not recognised by logic, but is resolved into predicate and copula, that is to say, into a noun which is affirmed or denied of another, plus the sign of that affirmation or denial.”
“The want of a copula is another instance of the primitive character of the tongue.”
“The copula is the sign denoting that there is an affirmation or denial; and thereby enabling the hearer or reader to distinguish a proposition from any other kind of discourse.”
A System Of Logic, Ratiocinative And Inductive (Vol. 1 of 2)
“Therefore the circumstance of time is properly considered as attaching to the copula, which is the sign of predication, and not to the predicate.”
A System Of Logic, Ratiocinative And Inductive (Vol. 1 of 2)
“The copula is the sign denoting that there is an affirmation or denial, and thereby enabling the hearer or reader to distinguish a proposition from any other kind of discourse.”
“_ -- In this system the formal relation is taken, that is, the copula may be any whatever.”
“He decided to use a very standard type of curve - the Gaussian copula, which is better known as a bell curve, or normal distribution - to map and determine the correlation on any given portfolio of assets.”
“Feel confuses people because it can serve either as a garden-variety transitive or intransitive verb or as a slightly more rarefied "copula," or linking verb.”

Looking for tweets for copula.

knitandpurl "Capitalism and religion, W. says. Or, in my case, failed capitalism and failed religion. Somehow, I'm the key to his project, W. says. Somehow I'm the key to the copula, though he's not sure how."
Dogma by Lars Iyer, p 12 Jun 8, 2012
ruzuzu I love the first example sentence:
"W hen I read the piece on Judge Roy Moore, I was treated to an amazing piece of trivia: the curious "fact" that the granite monument, while on the road, was subject to "what truckers call 'fuck bugs' (Plecia nearctica to entomologists), which swarm in copula for hours at a time, especially near the Gulf, and as a consequence — truckers and entomologists agree — make twice the splat of anything else you're likely to encounter.""
