long-standing
UK: ˌlɒŋˈstændɪŋ | US: ˌlɔːŋˈstændɪŋ
adj. existing or continuing for a long time
adj. having a long history or tradition
The word combines "long," from Old English lang (extended in duration), and "standing," from Old English standan (to remain upright or endure). The suffix "-ing" transforms the verb "stand" into a participial adjective, creating a compound meaning "enduring for a long time." The logic reflects physical endurance metaphorically extended to temporal persistence.
