conjugation (linguistics)

The scheme of inflections which mark contrasts of tense, person, and number in verbs. Latin and Greek had complex conjugational systems; English has very few verbal inflections (eg -ing, -ed, -en); by comparison, French and German are intermediate in complexity.

Latin conjugation, Spanish conjugation and the English verb, each with complex conjugation forms. see also conjugate element (field theory). A conjugate in algebra is similar to a complex conjugate, but is used to rationalize the denominator of a fraction. See inner automorphism, conjugacy class, conjugate closure, and conjugation of isometries in Euclidean space. Topological conjugation, which identifies equivalent dynamical systems. Conjugate points, in differential geometry. Conjugate prior, in probability theory, a family of prior probability distributions.

In science:

Bacterial conjugation, in biology, transmission of DNA between cells by contact other than fusion. Conjugated system, in organic chemistry, a system of atoms covalently bonded. In immunology, a Conjugate vaccine Conjugate variables (thermodynamics), the internal energy of a system. In metabolism, conjugation is a biochemical process to bind a substance to an acid and thereby deactivating its biological activity, making it water-soluble, and facilitating its excretion. Conjugate quantities, in quantum physics, are observables that are linked by the Heisenberg uncertainty principle, such as position and momentum.
