What is kestrel? How to use in English

The word "kestrel" is an Old English term that has been passed down through the centuries to describe a small bird of prey, commonly found in open country and grasslands. The origin of the word is uncertain, but it is believed to have come from the Old English word "cystril," which likely derives from a Germanic language. The most popular theory suggests that "cystril" is a compound word consisting of "ciost," meaning "narrow," and "ral," meaning "sparrowhawk." This would give us a bird that is a "narrow sparrowhawk." Another theory suggests that the word "cystril" could be derived from the Old English word "cestra," which means "bluestone," and "hryge," which means "crest." This would result in a bird called a "bluestone crested." There is also a theory that the word "cystril" is an adaptation of the Latin word "clamida," meaning "clawed." This theory would imply that the kestrel was known for its distinctive curved talons. Whatever the origin of the name, the kestrel remains a symbol of open country and a reminder of the enduring link between language and nature.
