as might be expected
遉 expresses the idea of something turning out just as one might expect, often with a nuance of 'as expected' or 'indeed'. The meaning is narrow and tied to this sense of predictable outcome.
遉 combines 辶 (movement) with 貞, which likely contributes a phonetic role. The exact historical development of the meaning 'as might be expected' from these components is uncertain.
The movement radical 辶 surrounds 貞, suggesting a path that leads to an expected result. Picture a journey where every step confirms what you already knew would happen.
For テイ, imagine taking a predictable path and arriving exactly on time at a tea (ティー) ceremony: tea -> テイ, and the outcome is just as expected.
