程度推到極端、很嚴重
把「沒有輕微、沒有緩和」用在事情的程度上：情況、天氣、難度都被推到很重、很極端的一端。
very bad, serious · adjective · B2
Very bad or very serious, used about problems, injuries, or illnesses.
嚴重的
核心畫面
A useful way to feel this word is 'all the softness taken out'. Whatever it describes has had its mildness, gentleness or give removed and pushed toward the harsh extreme — a problem with no small side to it, weather with no let-up, a face with no smile. From that one feeling grow both the 'very intense / very serious' senses and the 'harsh and unyielding' senses.

抓這個字有一個好用的感覺：「把柔軟的部分全抽掉」。它形容的東西，溫和、緩和、留餘地的那一面被拿走了，整個推向最嚴酷的一端——一個沒有輕微可言的問題、一場毫不放鬆的天氣、一張不帶笑的臉。從這一個感覺，同時長出了「很強烈、很嚴重」和「嚴厲、不留情」兩條線。Three branches
對人嚴厲、不留情
把「抽掉柔軟」用在對待人的態度上：不放寬、不帶暖意、不留情面。處罰、批評、還有一個人的性子，都可以是這種硬邦邦、不通融的嚴。
strict, stern · adjective · B2
Behaving in a strict, unfriendly way, without warmth or kindness.
嚴肅的、不苟言笑的
樸素無裝飾
同樣是「把柔軟、多餘的東西拿掉」，這回用在外觀上：一切修飾都被剝乾淨，只剩最素、最直的樣子。
plain, unadorned · adjective · B2
Very plain and simple, with little or no decoration.
樸素的、簡樸的
