易

• Change/Exchange: The material act of swapping or bartering (trade, tribute); a transformation of state, mind, or condition; the cosmological principle of universal fluctuation and rhythmic interplay.
• Easy: A state characterized by a lack of difficulty; effortless. In later texts, this may lean toward "trivial" or "simplistic."

• Transitive Verb: When followed by a direct object (e.g., 易之), it typically means "to change" or "to exchange."
• Predicate/Adjective: When appearing as a predicate or at the end of a clause, it is ambiguous and may mean either "is easy" (adjective) or "has changed" (intransitive verb).

• Contrast: The presence of 難 (difficult) strongly indicates the "easy" sense.
• Lexical Shift: In early texts, this glyph carries the full semantic load for exchange/swap; in later texts, 換 often reinforces or replaces this specific usage.

The glyph represents two distinct semantic roots. The translator must first determine if the context demands a process (change) or a quality (ease).
