1. To join together; specifically, to join in marriage; unite by marriage.
2. In grammar, to inflect (a verb) through all its various forms, as voices, moods, tenses, numbers, and persons, or so many of them as there, may be. This use has its origin in the fact that in inflected languages a verb is conjugated by conjoining certain inflectional syllables with the root.
3. In biology, to perform the act of conjugation; specifically, in botany, to unite and form a zygospore.
4. United in pairs; joined together; coupled.
5. In botany, applied to a pinnate leaf which has only one pair of leaflets.
6. In chem., containing two or more radicals acting the part of a single one.
7. In grammar and rhetoric, kindred in meaning as having a common derivation; paronymous: an epithet sometimes applied to words immediately derived from the same primitive.
8. In mathematics, applied to two points, lines, etc., when they are considered together, with regard to any property, in such a manner that they may be interchanged without altering the way of enunciating the property—that is, when they are in a reciprocal or equiparant relation to one another.
9. n. In gram, and rhetoric, one of a group of words having the same immediate derivation, and therefore presumably related in meaning; a paronym. In logic, an argument from conjugates is one drawn from the obvious similarity of such words in form, and, it is assumed, in signification also.
10. n. In chem., a subordinate radical associated with another, along with which it acts as a single radical.
11. n. A conjugate axis.
12. In gearing, said of tooth-profiles when they are of such a form that one will drive the other with a constant velocity-ratio, that is, when the ratio of the angular velocity of the driver to that of the driven is constant. The necessary condition for a constant velocity-ratio is that a normal to the two curves at the point of contact shall cut the straight line joining the centers of the gears at the point where it is intersected by the two pitch-circles.
13. United by a transverse furrow, as the paired ambulacral pores of the echinoids.
14. n. Of a point O with respect to the triangle ABC, a point O′ such that on it are copunctal AX′ , BY′ , CZ′ when X′ , Y′ , Z′ are the isotomic conjugates, with respect to the sides, of X, Y, Z the points where transversals from A, B, C through O meet the sides.
