1 [with object] Grammar Give the different forms of (a verb in an inflected language) as they vary according to voice, mood, tense, number, and person.
Example sentences
  • A French language lesson follows with the Brother conjugating the reflexive verb deshabiller, ‘to undress’.
  • Tenses are confused, verbs are conjugated and there's a creek to swim in to give relief from the merciless sun.
  • In a month, they were writing the alphabet, conjugating verbs, and making small sentences.
2 [no object] Biology (Of bacteria or unicellular organisms) become temporarily united in order to exchange genetic material: E. coli only conjugate when one of the cells possesses fertility genes
More example sentences
  • The phh1 single mutant is not completely sterile but is nearly sterile, whereas the msa1 deletion mutants conjugated efficiently even in nutrient-rich medium.
  • This is essential to the survival of ciliate lineages; most ciliates cannot reproduce indefinitely by asexual fission, and eventually die out if prohibited from conjugating.
  • The solid line designates a plasmid that conjugates slowly but imposes a low cost of carriage, whereas the dashed line indicates a faster-conjugating plasmid that imposes a higher cost.
2.1(Of gametes) become fused.
Example sentences
  • Under the same conditions, wild-type cells conjugated and succeeded in producing spores.
  • Haploid cells conjugated to form zygotes, which then underwent meiosis.
3 [with object] Chemistry Be combined with or joined to reversibly: bilirubin is then conjugated by liver enzymes and excreted in the bile
More example sentences
  • After estrone hydroxylation, the various poly-hydroxy derivatives are conjugated with glucuronate or sulfate, or methylation occurs prior to excretion in urine.
  • Fluorescein is frequently conjugated to macromolecules via lysine residues using an isothiocyanate derivative or to sulfhydryl groups via a variety of chemistries.
  • In the liver it is conjugated with glucuronate which renders it water soluble.


Pronunciation: /ˈkänjəɡət/
1Coupled, connected, or related, in particular.
Example sentences
  • One secondary terminal is connected directly to the spark plug of the parent cylinder while the other is connected to the second spark plug of the conjugate cylinder.
  • The conjugate phrase, ‘operates to a significant extent for the benefit’, directs attention to certain features of the Trust.
  • The principles governing the seismic behavior of structures are the conjugate laws of equilibrium and compatibility, and force-displacement relationships of structural components.
1.1 Chemistry (Of an acid or base) related to the corresponding base or acid by loss or gain of a proton.
Example sentences
  • Of course, one can change the pH of the buffer by selecting other concentrations of acid and conjugate base, but the range of pH values over which a given buffer functions most effectively are close to the pK a of the acid.
  • The most common buffers are mixtures of weak acids and their conjugate bases.
  • In other words, the term pK a is that pH at which an equivalent distribution of acid and conjugate base (or base and conjugate acid) exists in solution.
1.2 Mathematics Joined in a reciprocal relation, especially having the same real parts and equal magnitudes but opposite signs of imaginary parts. Short for complex conjugate.
Example sentences
  • The quartic in y must factor into two quadratics with real coefficients, since any complex roots must occur in conjugate pairs.
  • He worked on conjugate functions in multidimensional euclidean space and the theory of functions of a complex variable.
  • Basically, the fifth coordinate was not observable but was a physical quantity that was conjugate to the electrical charge.
1.3 Geometry (Of angles) adding up to 360°; (of arcs) combining to form a complete circle.
1.4 Biology (Especially of gametes) fused.

Pronunciation: /ˈkänjəˌɡāt/
1A thing that is conjugate or conjugated, in particular.
Example sentences

  • Now, in some languages, when the verb conjugates are varied, you can omit pronouns, because you know the person and number from the verb alone.
1.1chiefly Biochemistry A substance formed by the reversible combination of two or more others.
Example sentences
  • Under similar experimental conditions, the carotene conjugate did not produce singlet oxygen.
  • Cytotoxicity of conjugates may be influenced by many factors, including drug loading, side-chain hydrophobicity and net charge, which may ultimately affect singlet oxygen generation.
  • However, very few proteins form stable ubiquitin conjugates.
1.2A mathematical value or entity having a reciprocal relation with another. See also complex conjugate.
Example sentences
  • There are two cams fixed on a common shaft that are mathematical conjugates of one another.



Pronunciation: /ˈkänjəɡəsē/
Example sentences
  • He is the first to introduce the notion of the order of an element, conjugacy, the cycle decomposition of elements of permutation groups and the notions of primitive and imprimitive.
  • The bending of a surface on a principal base is a continuous bending of a surface under which the conjugacy of the net of certain curves on the surface is preserved.…
  • But first we need the following basic notion of conjugacy of group actions.


Pronunciation: /ˈkänjəˌɡātiv/
Example sentences
  • The improvement is generally not due to changes in the rate constant of conjugative transfer or in the cost of plasmid carriage, which can be estimated as the difference between recipient and donor growth rates.
  • This ‘amplification effect’ could have an impact on the evolution of bacterial pathogens that exist in heterogeneous bacterial communities because conjugative plasmids can carry virulence or antibiotic-resistance genes.
  • Furthermore, many of the agents of exchange (bacteriophages, transmissible and conjugative plasmids) are themselves best viewed as selfish elements.


Late 15th century (as an adjective): from Latin conjugat- 'yoked together', from the verb conjugare, from con- 'together' + jugum 'yoke'.
