The spelling of "builded overnight" may seem unusual, but it is actually an archaic form of the past tense of "build." In IPA phonetic transcription, it is pronounced as /ˈbɪldɪd/. This form was commonly used in older English texts but has since been replaced by the more modern "built." English is a language that evolves over time, and while "builded overnight" may sound strange to modern ears, it is a reminder of the language's rich history and development.
The phrase "builded overnight" is not a commonly used phrase in English. The correct past tense of the verb "to build" is typically "built". However, if you are referring to the phrase "built overnight", the etymology of the word "built" can still be explained.
The word "built" comes from the Old English word "byldan" which means "to build" or "to construct". It is derived from the Proto-Germanic word "*buldaną". This word shares a common ancestor with other Germanic languages, such as Dutch "bouwen" and German "bauen".
The Indo-European root of "build" is believed to be "*bʰuH-", which carries the basic meaning of "to dwell" or "to exist".
