The spelling of the word "tarwell" may seem peculiar, but it can be easily explained using phonetics. The first syllable, "tar," is pronounced as /tɑː/, with a long "a" sound. The second syllable, "well," is pronounced as /wɛl/, with a short "e" sound. Together, the word is pronounced as /tɑː.wɛl/. While the origins of the word are not immediately clear, it is likely a combination of "tar", a black, viscous substance, and "well", a hole drilled in the ground to extract oil. Therefore, "tarwell" may refer to a well used to extract tar or a well containing tar.
