When “迷” fills a head
Why it is in the set
Because the double meaning is a gift. One character covers the person standing at a junction and the person standing in front of an open fridge, and in a joke generator that ambiguity does the work of two. It is also the character the site uses on its own error pages, which felt right.
What a head full of it looks like
Opening the same two tabs repeatedly. Asking someone else to choose and then arguing with their choice. Deciding to decide later. A head led by 迷 is not short of options; it is short of a reason to prefer one.
Words that use it
迷う (mayou, to hesitate or be lost), 迷子 (maigo, a lost child), 迷惑 (meiwaku, trouble caused to someone else), 迷路 (meiro, a maze), 迷信 (meishin, a superstition).
Kanji it turns up with
悩 (worrying) is its near-twin and the two together are read as one state. 迷 leading with 旅 (travel) behind it is the only combination where the literal meaning comes back, and the quips use it.
Where “迷” comes from
The road radical 辶 underneath, and 米, rice, on top for the sound. A road, and a sound: the road you cannot find your way along.
辶 is one of the most useful radicals to recognise. It appears in 道 (a way), 進 (to advance), 送 (to send), 逃 (to escape) — anything to do with going.
Japanese uses 迷う for losing your way in a town and for being unable to choose from a menu, with no change of word at all.
A line you might get for “迷”
“Two options, equally fine. Forty minutes gone.”
