(Crystallography) The intergrowth of two crystals: Describing a process where two crystals of the same substance grow together in a symmetrical fashion.

Usage and Examples

Advanced Usage

• "Twinning" as a concept can be applied metaphorically to describe the close pairing or parallel development of two similar things, such as ideas, projects, or cities (e.g., sister cities). However, in formal or technical contexts, the adjectival forms are more standard.

Notes on Different Meanings

The primary meaning relates to biological reproduction. The specialized meaning in crystallography is distinct but shares the core idea of two identical or mirrored units forming a pair. The informal modern use relating to wearing matching outfits ("outfit twinning") is a derivative of the verb "to twin" and not the primary adjectival meaning defined here.
