inoffiziell vs offiziell
official
'offiziell' and 'inoffiziell' are direct opposites. Use 'offiziell' when something has been confirmed, approved, or made public by the responsible body. Use 'inoffiziell' when something has not yet been confirmed, or is known only casually, privately, or unofficially. Sometimes something is already clear 'inoffiziell' (unofficially), but has not yet been formally decided. The difference is important for news, results, roles, and decisions.
