逮

• Physical capture: To seize, catch, arrest, or overtake; typically denotes the successful conclusion of a pursuit.
• Spatial/Temporal attainment: To reach, arrive at, or attain a specific destination or point in time. In later classical prose, this may function as "by the time that..." or "when [a state] was reached."

• Transitive verb: Used as a verb of action (to catch/reach).
• Temporal marker: When paired with time-words or states of being, it can function as a conjunction meaning "until" or "when."

Contrast with 及 (jí): While both mean to reach or attain, 逮 frequently retains the nuance of pursuit or culmination—the act of finally closing a distance—whereas 及 is more general.

• U+8FE8: A graphic variant with no semantic distinction from the standard glyph.
