Doublets: One Root, Two Paths into English

Explore pairs of English words that came from the same source by different routes.

A doublet is a pair of words that share an origin but entered English by different paths, so they now differ in form and meaning. Often one came directly from Latin and the other came earlier through French, which had worn the word down. Latin fragilis gave us 'fragile' directly and 'frail' through French. Latin regalis gave 'regal' directly and 'royal' through French. Latin hospitale gave both 'hospital' and, through Old French hostel, 'hotel. ' Worked example: 'The elderly man was frail, so the vase seemed less fragile than he was.

' Both words describe something easily broken, but frail is used for people's bodies and health, while fragile suits objects, situations, or ecosystems. Doublets show how one root can split into related but distinct meanings. When two words feel strangely similar, a doublet may explain why.
