I think there's associative and association and associations
I believe the root words are league and collaboration...though I am not sure.
associate
The words "associate," "associative," and "disassociate" share the same root word as "association." They all derive from the Latin word "associare," meaning "to unite or join together."
The root word of sociable is "socius," which is Latin for "companion" or "associate."
The root word for "conversation" is "converse," derived from the Latin word "conversari," which means "to associate with."

No, "sary" is not a root word in the English language. Root words are the base form of a word from which other words are derived.
