durum
UK[ˈdjʊərəm]US[ˈdʊrəm]
n
A hard variety of wheat, having a high protein and gluten content, used especially to make pasta.
Etymology
The word 'durum' is a modern Latin term, taken directly from the neuter form of the Latin adjective 'durus', meaning "hard". This adjective itself descends from the Proto-Indo-European root deru-/dreu-, which carried the core meaning of "to be firm, solid, steadfast". This root is also the source of English words like 'tree' (originally solid wood), 'true', and 'endure'. The logic of the name is perfectly literal, describing the key characteristic of this wheat species: its kernels are much harder than those of common bread wheat. Thus, the word's journey from an ancient root for solidity to a specific modern agricultural term is a clear and direct example of descriptive naming.
Analysis
The word is a simplex loanword. It is a direct borrowing from Latin, where it functioned as a neuter adjective meaning "hard".
