The spelling of "rarely done" is relatively straightforward when using the International Phonetic Alphabet (IPA). The first syllable is pronounced as /rɛər/ with an "air" sound, while the second syllable is pronounced as /li/ with a short "i" sound. The final syllable, "done," is pronounced as /dʌn/ with a short "u" sound. When combined, the word is pronounced as /rɛərli dʌn/ and means something that is infrequently or almost never done.
The word "rarely" is derived from the Old English word "hrēre" which meant "seldom" or "infrequently". Over time, it evolved into "Rayrliche" in Middle English, and eventually became "rarely" in modern English. The word "done" is derived from the Old English word "don", which means "to do" or "to perform". It has its roots in the Proto-Germanic word "dōną".
