THE LEXICIDION.
Acute, conies from acuo, acuere, to sharpen ; and is said of an angle whose including
sides, the more that its measure is lesse then a quadrant, have their concursive and
angulary point the more penetrative, sharp, keen and pierceing. Whence an acut-
angled triangle.
Adaquat, is that which comprehendeth to the full whatever is in the thing to the
which it is compared ; and, for the most part, in my Trissotetras is said of the
general finall resolvers, in relation to the moods resolved by them. It is compound-
ed of ad and aequo, (square, parem facere, to make one thing altogether like, or
equall to another.
Adjacent, signifieth to he neare and close, and is applyed both to sides and angles ; in
which sense, likewise, I make use of the words, adjoyning the, conterminat, or eon-
terminall with, annexed to, intercepted in, and other such like, for the more va-
riety, as adherent, bounding, bordering, and so forth. It comes from adjaceo,
adjacere, to lie neere unto, as the words ad and jaceo, which are the parts whereof
it is compounded, most perspicuously declare.
Additionally is said of the line, which in my comment is indifferently called the line
of addition, the line of continuation, the extrinsecall line, the excesse of the secant
above the radius, the residuum, or the new secant. It comes from addo, addere,
which is compounded of ad and do, to put to and augment.
Affection, is the nature, passion, and quality of an angle, and consisteth either in the
obtusity, acutenesse, or rectitude thereof. It is a verball from officio, affeci, affec-
tum, compounded of ad and facio.
Aygregat, is the summe, totall, or result of an addition ; and is compounded of ad
and grex ; for as the shepheard gathers his sheep into a flock, so doth the arithme-
tician compact his numbers to be added into a summe.
