Solemnity
Gravity
noun, な adjective
A villa that's kept under really strict rules will press solemnity on everyone who tries to stay there.
そうごん
This is a jukugo word that uses the on'yomi readings of the kanji. You didn't learn this reading for 厳 yet, so here's a mnemonic to help you:
To help you understand the solemnity of a moment of silence, usually a gong (ごん) will play a few times. As you listen to the echo and silence that comes after it. The gravity of what you're being silent for really sinks in.
その儀式は荘厳に行われました。
The ceremony was held solemnly.
