Jointly

Together, with responsibility, ownership, or action shared by two or more parties.

Reach for it when describing genuine co-ownership rather than consultation alone

The two schools jointly created a garden for the neighborhood.

• playful

  side by side

  visible companionship and parallel effort deserve emphasis

  not when Side by side may mean proximity without shared responsibility.

• everyday

  together

  shared presence or action is enough

  not when Together does not specify shared authority, liability, or ownership.

• warm

  in partnership

  an ongoing relationship supports shared work

  not when Partnership implies a durable arrangement beyond one joint action.

• professional

  collaboratively

  participants actively shape the work through cooperation

  not when Collaboration can occur while one party retains final control.

• professional

  cooperatively

  parties work helpfully toward a compatible result

  not when Cooperation does not necessarily divide decision rights equally.

• formal

  collectively

  a group acts or is considered as a whole

  not when Collectively can diffuse individual duties that jointly remain explicit.

• separately
• independently
• unilaterally

• jointly owned

  The workshop is jointly owned by its workers and neighborhood trust.

• jointly responsible

  Both contractors are jointly responsible for documenting the repair.

• jointly developed

  The curriculum was jointly developed with working apprentices.
