In chemistry, polyvalency (or polyvalence, multivalency) is the property of molecules and larger species, such as antibodies, medical drugs, and even nanoparticles surface-functionalized with ligands, like spherical nucleic acids, that exhibit more than one supramolecular interaction.
Polyvalence or polyvalent may refer to: Polyvalency (chemistry), chemical species, generally atoms or molecules, which exhibit more than one chemical valence; Polyvalence (music), the musical use of more than one harmonic function of a tonality simultaneously; Polyvalent antibody, a group of antibodies that have affinity for various antigens
Polyvalence or multivalence refers to species that are not restricted to a specific number of valence bonds. Species with a single charge are univalent (monovalent). For example, the Cs + cation is a univalent or monovalent cation, whereas the Ca 2+ cation is a divalent cation, and the Fe 3+ cation is a trivalent cation.
Polytonality (also polyharmony [1]) is the musical use of more than one key simultaneously. Bitonality is the use of only two different keys at the same time.Polyvalence or polyvalency is the use of more than one harmonic function, from the same key, at the same time.

Polysemy (/ p ə ˈ l ɪ s ɪ m i / or / ˈ p ɒ l ɪ ˌ s iː m i /; [1] [2] from Ancient Greek πολύ-(polý-) 'many' and σῆμα (sêma) 'sign') is the capacity for a sign (e.g. a symbol, a morpheme, a word, or a phrase) to have multiple related meanings.
