The word "availables" is not found in standard English dictionaries as a noun. However, if you are referring to the plural form of the word "available", its etymology can be traced as follows:
The word "available" originated from the French word "avalaile" in the 15th century, meaning "that can be used". It is derived from the Old French term "availlier", which means "to be of worth" or "to have influence". The Old French term is ultimately derived from the Latin word "ad valere", where "ad" means "to" and "valere" means "to be strong" or "to be of worth".
Over time, "avalaile" evolved into "available" in English, retaining the meaning of "that can be used" or "that is accessible".
