prudence, thought, concern, consider, deliberate, fear
慮 centers on careful mental processing: thinking something through, weighing concerns, and acting with prudence. The fear sense is a natural extension of worrying about outcomes.
慮 combines 虍 (tiger) with 思 (think). The tiger component likely contributes sound, while 思 provides the core meaning of thinking or considering. The exact historical development is uncertain, but the phono-semantic structure is broadly accepted.
A tiger (虍) sits outside while you think (思) inside. To survive, you must carefully consider every move—that's prudence and concern.
For リョ, imagine a thoughtful lion (ライオン) pondering its next move: lion -> リョ, and the lion's careful deliberation matches the kanji's meaning.
