illustrate
譬 centers on making something clear by comparing it to something else: illustrating a point through analogy or example.
譬 combines 辟 (a component associated with law or pattern) with 言 (speech), suggesting using words to set forth a pattern or comparison. The exact historical development is uncertain.
The top 辟 looks like a ruler or pattern, and the bottom 言 is speech. Imagine using words to lay out a pattern that makes an idea clear: illustrating through comparison.
For ヒ, picture a teacher saying 'He illustrates the point' while pointing at a diagram: 'He' -> ヒ, and the speech 言 below the pattern 辟 makes the illustration.
