And you copy-pasted them right from JMDict, you naughty boys 👀 😂
The meanings listed are "ridicule; laziness", both of which are at best very tenuous.
I guess it caught my attention because neither seems to have anything to do with 「我慢」, which is first word NS teaches with this kanji.
Something about this seemed especially weird, so I spent a while looking up the words that use it and found the following, with frequency scores as reported by DaKanji (subtract 9 to get the base-10 logarithm of frequency in their corpus, e.g. 4.73-9=-4.27 is approx. once per 19,000 words):
我慢 がまん endurance 4.73
自慢 じまん pride 4.42
傲慢 ごうまん arrogant 3.72
慢性 まんせい chronic 3.71
怠慢 たいまん neglect 3.19
慢心 まんしん conceit 2.97
高慢 こうまん arrogant 2.94
緩慢 かんまん slow 2.65
侮慢 ぶまん insult 1.64
驕慢 きょうまん arrogant 1.48
暴慢 ぼうまん ill-mannered -
That's everything I found, not including further compounds and expressions, so I propose changing the flashcard to "pride; sluggish".
よろしくお願いサメ!
