Etymology
the word 'jointly' is a straightforward formation from the adjective 'joint', which entered english from old french. the french term 'joint' is the past participle of 'joindre', itself derived from the latin verb 'iungere', meaning 'to join, yoke, or connect'. this latin root is part of a widespread indo-european family relating to joining, seen in words like 'yoga' and 'yoke'. the adverbial suffix '-ly' is of germanic origin, added to adjectives to indicate manner. therefore, 'jointly' literally means 'in a joined manner', directly preserving the core concept of collective action or shared state from its latin ancestor.
