Community
A community is a small or large social unit (a group of living things) who have something in common, such as norms, religion, values, or identity. Communities often share a sense of place that is situated in a given geographical area (e.g. a country, village, town, or neighborhood) or in virtual space through communication platforms. Durable relations that extend beyond immediate genealogical ties also define a sense of community. People tend to define those social ties as important to their identity, practice, and roles in social institutions like family, home, work, government, society, or humanity, at large. Although communities are usually small relative to personal social ties (micro-level), "community" may also refer to large group affiliations (or macro-level), such as national communities, international communities, and virtual communities.
Practitioner
A practitioner is someone who is qualified to or registered to practice a particular occupation, profession, or religion. Practitioners who are in a particular area may be referred to as a specialist or advanced practitioner. The medical and social care professions use these titles to distinguish the level of qualifications, competency, and training a practitioner undertakes.
