Biconjugate, spelt /ˌbaɪkənˈdʒuːɡət/, is a mathematical term that refers to the conjugate of a conjugate of a matrix or a quaternion. The term biconjugate can be broken down into two parts - "bi" meaning "two" and "conjugate" meaning "forming a pair by exchanging two distinguished elements". The correct spelling of biconjugate involves the use of the prefix "bi-" to indicate two conjugates. The phonetic transcription helps to clarify the pronunciation of each syllable in the word.
Biconjugate is an adjective used to describe a mathematical property or operation that is symmetric with respect to two different conjugation processes. In mathematics, conjugation generally refers to a process of transforming an object, such as a matrix or a complex number, by replacing its elements with their respective conjugates. The concept of biconjugate extends this notion by considering two distinct conjugation processes.
In linear algebra, the term "biconjugate" is often associated with the biconjugate transpose of a matrix. The biconjugate transpose of a matrix is obtained by taking the conjugate transpose of both the matrix and its elements, resulting in a matrix with its elements and the matrix itself all conjugated.
In the context of quantum mechanics, particularly quantum fields, biconjugate refers to an equation or a property that remains invariant under both charge conjugation and time reversal. This means that the equation or property remains the same when the direction or flow of time is reversed and when the charges of particles involved are swapped.
Overall, the term biconjugate highlights the symmetry in mathematical operations under two distinct conjugation processes, either in linear algebra through the biconjugate transpose of a matrix, or in quantum mechanics through equations or properties that are invariant under both charge conjugation and time reversal.

The word "biconjugate" is derived from the combination of the prefix "bi-", which means "two" or "having two", and the word "conjugate". The term "conjugate" comes from the Latin word "conjugare", which means "to join together" or "to unite". In mathematics, "conjugate" is often used to refer to pairs of complex numbers that share certain properties. By adding the prefix "bi-", the word "biconjugate" indicates that there are "two" conjugates involved.
