means To be filled with wonder or astonishment at something, or the thing itself that prompts such wonder.

from From Latin 'mirabilia,' meaning 'wonderful things,' the plural of 'mirabilis' ('wonderful'), which traces back to 'mirari,' to wonder at or admire. It traveled into English through Old French 'merveille,' a sibling of 'miracle' and 'mirror' — all rooted in that same Latin 'mirari,' the act of looking with astonishment. So at its heart, a marvel is simply something you cannot stop staring at.
