lie, falsehood
嘘 centers on spoken untruth: a lie or falsehood, typically conveyed through words.
嘘 combines 口 (mouth) with 虚, which likely contributes the sound and the idea of emptiness or hollowness, suggesting empty words.
A mouth 口 speaking empty, hollow things 虚: that is a lie.
For キョ, imagine a lie so big it echoes like a loud 'kyo!' in an empty hall: kyo -> キョ, and the hollow sound matches the empty words.
