But historians are not so sure.
Circle The Latin root of the word circle is circus. The traditional shape of the large roofless enclosures in which the famous Roman Chariot races were run was circular or oblong, and thus the word came to described this shape as well.
Congruent The Latin word congruere meant "coming together" or "working together".

I learned from Glen Woodburn recently that, "Actually, gruere comes from the latin word grui which means to be in harmony with. So congruent translates to mean together in harmony with. Nathan refers to Common Notion 4 in Book one, which Heath translates as "Things which coincide with one another, are equal to one another.
In a note to the Math Hisotry list J. Cabilon wrote that "Christoph Clavius ? Hinc enim fit, ut aequalitas angulorum ejusdem generis requirat eandem inclinationem linearum, ita ut lineae unius conveniant omnino lineis alterius, si unus alteri superponatur.
Ea enim aequalia sunt, quae sibi mutuo congruunt. In particular he says that, "In English, writers commonly refer to geometric figures as equal as recently as the nineteenth century. Two triangles are equal, when an angle and the two sides which contain it, in the one, are respectively equal to an angle and the two sides which contain it, in the other.
It is sometimes used with the wave inverted also. Leibniz used a tilde with a single underline as a unique symbol for congruence, but so many symbols were in use that it did not catch on.
According to Cajori, the use of the modern symbol for congruence became the accepted practice around the beginning of the 20th century. He suggests the first use was by G. Hill and George B Halstead. The symbol is still not universally accepted and was not used in England at the time of his writing because of confusion with the tilde symbols use for difference.
According to a post from Herbert Prinz, "In modern English texts on navigation, nautical astronomy or its history, the tilde is frequently used to express the function a - bwhere x stands for absolute value. Cotter, The Complete Nautical Astronomer, I am not sure when this practice started.
In older texts on the same subject, say, Moore, The Practical Navigator,one does not find the tilde used in this way. For one, because instructions were given mostly verbally without the use of any symbols at all. Congruent Numbers was a brand new term to me when I read a neat blog at Bit-Player about it after a recent news release from AIM American Institute of Mathematics announced that all the congruent numbers up to 1 trillion have been enumerated.
Well, job done I guess. The blog is so well written that I am not about to try to replicate all that good work, go read it.
If you want more, here is a link from the AIM on the topic. Conjugate is the union of the common Latin prefix com together and the root juge yoke and means to bind together in a pair. Mathematically it is often used for things that are opposites in some way, as in the complex conjugates.
The same word in grammar refers to words of a common origin and related meaning, and in biology to an act of sexual union, for which the more common term is conjugal relations. The literal meaning is "to turn away". The verb converse as in conversationwhich has the same spelling, is from a completely different root.
Dean The term now used for the head of a department or faculty at a college is derived from the Latin deaconus which meant "chief of ten". The similar sounding deacon, for a church leader, is not related and comes from the Greek root diakonos for a servant.
According to John Conway, the literal meaning is "one who raises the dust". · The student will be able to take a word problem, form a model/diagram, write an equation and solve the equation feeling confident about their model and use of mathematics.
