arise
謖 centers on the act of rising or standing up, often with a sense of dignity or formality. The single given meaning 'arise' captures this straightforwardly.
謖 combines 言 (speech) with 畟, which likely contributes the sound and may relate to rising or standing. The exact historical development is uncertain.
The left side 言 (speech) and the right side 畟 (a shape suggesting rising) together evoke words that make someone stand up, as if a formal command causes a person to arise.
For ショク, imagine a shock of a formal speech that makes everyone arise: shock -> ショク, and the words 言 cause the rising.
