portabella
UK[ˌpɔːtəˈbelə]US[ˌpɔːrtəˈbelə]
n
A large, mature, dark brown cremini mushroom with a thick cap and a rich, meaty flavor.
Etymology
The word 'portabella' entered English in the late 20th century as a marketing term for a mature cremini mushroom, borrowing directly from the Italian 'portabello' or 'portabella'. The Italian origin is obscure; one popular but unverified folk etymology suggests it means "beautiful door" or "beautiful to carry," from 'porta' (door) or 'portare' (to carry) and 'bello' (beautiful). Another theory links it to Portobello Road in London, known for its markets. Regardless of its contested Italian roots, the word's journey into English is a straightforward case of lexical borrowing for a specific culinary item, where the original foreign form was adopted wholesale without morphological analysis, capitalizing on its exotic and appealing sound to denote a premium food product.
Analysis
This word is a modern English coinage and a loanword from Italian. It is not productively segmented into meaningful English morphemes. The Italian word 'portabello' (sometimes spelled 'portabella' in English) is itself a compound, but its etymology is uncertain and debated. It may derive from 'portare' (to carry) + 'bello' (beautiful), or it may be a place name. The English borrowing treats it as a simplex lexical unit.
Examples
The recipe calls for portabella mushrooms to be grilled and served as a vegetarian burger.
