The correct spelling of the word "leaved altar" should be "leaved altar". The pronunciation of "leaved" is "liːvd" and refers to something that has leaves, whereas "leave" is pronounced "liːv" and means to go away from. IPA transcription is important in this case, as the two words are pronounced identically except for the final sound. Therefore, it is crucial to spell "leaved altar" correctly to avoid miscommunication and confusion.
The phrase "leaved altar" does not have a specific etymology. "Leaved" is the past participle form of the verb "leave", meaning to depart or go away. On the other hand, an "altar" is a raised structure used in religious ceremonies. However, the combination of these words, "leaved altar", appears to be a combination of an adjective (leaved) and a noun (altar) which, in this context, does not convey a specific meaning.
