The etymology of the phrase "long period" can be broken down as follows:
1. Long: The word "long" originated from the Old English word "lang" which meant "having considerable linear extent in space" or "extending for a considerable distance". It can be traced back to the Proto-Germanic word "langaz".
2. Period: The word "period" derives from the Latin word "periodus", which came from the Greek word "periodos". In Greek, "peri" means "around" and "odos" means "way" or "journey". Thus, "periodos" referred to a journey around or a circuit. In English, "period" initially meant a recurring or completed cycle, a specific portion of time, or a fixed stage or phase.
When these two words combine, "long period" refers to a significant length of time or a lengthy span or duration.
