Etymology

弟 originally depicted a cord or thong wrapped around a weapon or tool, later borrowed for 'younger brother' and extended to ideas of order and respect toward elders.

Meaning mnemonic

The top stroke 丿 looks like a protective older sibling, and the inner part 弚 resembles a smaller figure with a bowing head—a younger brother showing respect.

Reading mnemonic

For テイ, imagine a younger brother taking a tea break with his elder: tea -> テイ, and the faithful service is shown by serving tea.
