The word "growth" dates back to the Middle English period, derived from the Old Norse word "grōa" meaning "to grow". This Old Norse term also has cognates in other Germanic languages, such as "groeien" in Dutch and "grüezen" in Middle High German.
The term "rate" comes from the Latin word "ratus", which means "reckoned" or "estimated". It is derived from the verb "reri" meaning "to think" or "to judge". The term "rate" has been a part of the English language since the late 15th century.
Therefore, the etymology of the phrase "growth rate" is a combination of the Old Norse word "grōa" and the Latin word "ratus", indicating the estimation or reckoning of the process of growth.
