Etymology: "Castrel" is a word for the kestrel, a small falcon, and it survives mainly in older English writing and in regional and dialect usage. Its story is one of a name travelling across Europe before it reached England. The source ties it to a family of words for the same bird: Latin "clisterella", Old French "crecel" and "cercele", French "crécerelle", and Neapolitan "castariello". Set side by side, these show a shared root that shifted shape from one language to the next, with the consonants rearranging as the name passed between speakers. The variety of forms across these languages reflects how often the bird was named and renamed in everyday speech, rather than a single fixed term passed down intact. English took its version from the French side of this family, so "castrel" sits among the bird names that arrived through Norman-influenced vocabulary alongside "kestrel" itself, which is the form that eventually became standard.
