The word "Sovenaunce" is an archaic term used in Middle English that refers to a reminder or a memory. It is pronounced /sɔ.ˈvɛn.əns/ with the stress on the second syllable. The spelling is unusual because it includes a "v" where a modern spelling would use a "u". This is because before the standardization of English spelling, "u" and "v" were interchangeable. The use of the "-aunce" suffix is also common in Middle English, which explains why the word is spelled with a "-aunce" ending instead of the modern "-ance".
The word "sovenaunce" has a Middle English origin. Its etymology can be traced back to the Old French word "souvenir" meaning "to remember" or "to recall". In turn, "souvenir" was derived from the Latin word "subvenire" which means "to come to mind". Over time, "souvenir" developed into "sovenaunce" in Middle English, still carrying the sense of remembrance or recollection.
