Tips

usage
The mēng reading (level tone) is the colloquial / spoken cluster — sneakier and more conversational than méng. Three uses: (1) to cheat — 蒙骗 (hoodwink), 瞎蒙 ('blind-cheat'), the casual ('don't bullshit me'); (2) to guess — 对了 / 答案 (guess the answer when you don't know it); (3) to be dazed / knocked-out — 发蒙 (be confused, blanking out), 蒙蒙亮 (first dim glimmer of dawn — 'still in a daze').
mistakes
Quick rule: rising tone is what's done TO someone (covered, blessed, wronged); level tone is what someone DOES (deceive, guess) or is in (dazed). 蒙蔽 (to deceive, formal/written) takes méng even though the meaning is similar to 蒙骗 — register difference, no logical fix; you just memorise the compound.

semantic

pig
Bottom (Kangxi #152) — pig under cover under foliage. The original picture was a wild boar hidden in undergrowth; classical Chinese lore held that boars curled up under brush were impossible to see, hence both 'covered up' and 'unable to discern' (蒙昧 ignorant, 启蒙 enlightenment = lifting the cover).
