liaises

Liaises is the third-person singular present tense of the verb liaise. To liaise means to establish and maintain communication between groups to facilitate coordination, information exchange, or collaboration. People liaise to ensure activities are aligned, problems are identified early, and decisions reflect the interests of those involved. Common contexts include business, government, diplomacy, construction projects, and non-governmental organizations.

The phrase typically follows the pattern liaise with someone or liaise with something. For example, "The coordinator liaises with suppliers to track delivery schedules." The related noun is liaison, referring to the act of liaising or to a person who performs that role.

Etymology: liaise derives from the French liaison, meaning a link or connection, from Latin ligatio or ligare, meaning to bind or connect.

In professional settings, liaison roles or officers formalize these activities, handling information flow, meeting coordination, and escalation of issues to maintain alignment among parties. Synonyms include coordinate, communicate, mediate, interface, and connect, though each carries slightly different nuance; liaise emphasizes ongoing contact and cooperation rather than unilateral action.
