surprise & confusion
矍 centers on a sudden, startled reaction: being taken by surprise and thrown into confusion. The given meaning "surprise & confusion" captures this single emotional state of being caught off guard and mentally unsettled.
矍 combines 瞿 (a startled, watchful look) with 又 (hand), suggesting a sudden, alert reaction. The exact historical development is uncertain, but the component relationship is consistent with the meaning of surprise and confusion.
The top part 瞿 looks like two wide eyes (目) peering out from a bird-like shape (隹), and the bottom 又 is a hand. Picture someone suddenly raising a hand to their face in shock, eyes wide with surprise and confusion.
For カク, imagine a sudden surprise that makes you exclaim "Cock!" (like a startled rooster sound): Cock -> カク, and the wide-eyed bird-like top reinforces the startled reaction.
