What does jointly mean?
The adverb jointly describes an action performed or responsibility held in common by two or more people, organizations, or parties. Saying that a proposal was “jointly approved” indicates that each participant had a role in approving it, while “jointly responsible” means that responsibility is shared rather than resting with only one party. The word is especially common in business, academic, governmental, and legal writing. It can also introduce a partner in a joint undertaking, as in “jointly funded by the council and a charity.” Although jointly clearly differs from acting separately, it does not necessarily mean that the partners contribute equally in money, time, authority, or effort. That distinction is particularly important in legal and financial contexts, where the precise allocation of duties or liability may depend on the surrounding agreement.

"The two universities jointly developed the new research programme."
"The directors jointly approved the proposal after reviewing the evidence."

The legal phrase “jointly and severally” makes shared responsibility explicit: each party may potentially be held responsible for the entire obligation.

Where does jointly come from?
English jointly was formed from joint with the adverbial suffix -ly. The adjective joint comes through Old French joint and ultimately from Latin iungere, meaning “to join” or “unite.” The same Latin root also underlies English words such as join, adjoin, junction, and conjunct, reflecting the broader family of words concerned with joining or connection.
How jointly is actually used
Common in formal, business, academic, and legal contexts. It emphasizes shared action or responsibility but does not by itself imply that contributions or ownership are divided equally.
