“association” in Latin

The English word association itself goes back to Latin sociō, through associātiō.

Riddle & Arnold A Copious and Critical English–Latin Lexicon, 1864

association
union, societas: to have formed a friendly association, societatem caritatis coiisse inter se.
A union of persons for a particular purpose: societas (for some common business: intellectual, commercial, etc.): sodalitas (a brotherhood; a union of companions; e.g., of certain priests at Rome; then of any similar association; e.g., of the free-masons): factio (a political party: mostly in a bad sense): collegium (a corporation; e.g., of merchants, priests, artisans, etc.).
“Association of ideas :” Hand thinks that associatio idearum must be allowed as a technical term.
