The phrase "spake about" is a combination of the Old English word "spake" and the preposition "about". Here is the breakdown of their etymology:
1. "Spake": "Spake" is the past tense of the Old English verb "sprecan" (modern English: speak). It is derived from the Proto-Germanic word "sprekaną", which means "to speak". The word "spake" was commonly used in Middle English and later fell out of use around the 16th century in favor of the modern English "spoke".
2. "About": The preposition "about" originated from the Old English word "abūtan" (ā + būtan), where "būtan" means "outside".
