host-guest

Who welcomes, welcomed

Host-guest describes a relationship or system where one entity (the host) contains, surrounds, or accommodates another (the guest).

The term appears most often in chemistry, where host-guest interactions involve molecules that fit together through shape and charge complementarity: host-guest complexes, host-guest chemistry.

The concept extends to materials science and supramolecular systems where containment or encapsulation matters.
