Etymology

Derived from Latin recurrere ("to run back"), combining re- (indicating repetition) and currere ("to run"). The root curr- appears in many English words (e.g., current, course), reflecting motion or progression. Over time, recurrent evolved to describe cyclical patterns in both literal (e.g., waves) and abstract (e.g., events) contexts.
