Etymology
the word 'mezzanine' entered english in the early 18th century directly from the italian 'mezzanino', which is a diminutive form of 'mezzano', meaning 'middle'. the italian term itself derives from the latin 'medianus', meaning 'of the middle', which comes from 'medius' (middle). the journey from the latin concept of 'middle' to the architectural feature is elegantly logical: a mezzanine is literally an intermediate or middle floor, inserted between two primary levels of a building. this term perfectly preserves its core semantic link to centrality and intermediacy, even as its application became specialized in english for describing specific interior architectural spaces.
Analysis
this word is a loanword adopted as a single unit from italian. it is not productively segmented using english morphemes.
