譯

Phono-semantic compound:

言 (말씀 언, “speech, words”) — semantic, indicating language and communication.

睪 (엿볼 역, “to peep, observe”) — phonetic, providing the sound 역.

The character thus denotes “rendering speech (言) according to observation (睪),” i.e., interpreting foreign or obscure words into comprehensible language.
