Correct spelling, explanation: the correct form is earring. The term earring refers to a piece of jewelry worn on the ear. The word is a compound noun formed from ear and ring, indicating its function and placement. Earing, on the other hand, is a less common term that can have different meanings, none of which are related to jewelry. Historically, earing could refer to the process of plowing or to an old nautical term related to reefing a sail. However, these uses are archaic and not commonly encountered in modern English. Therefore, when referring to the piece of jewelry, earring is the correct and commonly accepted form.
