门槛上的——已不在原处、又未到别处的那段中间状态：候机厅、毕业的那个夏天、凌晨的酒店走廊。 On the threshold — no longer where you were, not yet where you're going.
On the threshold — no longer where you were, not yet where you're going. 门槛上的——已不在原处、又未到别处的那段中间状态：候机厅、毕业的那个夏天、凌晨的酒店走廊。
词源etymology
拉丁语 limen（门槛）→ liminal。字面就是「门槛上的」—— 一只脚已抬起，另一只还没落地的那个位置。
Latin limen (threshold) → liminal. Literally “of the threshold” — the position where one foot has lifted and the other has not yet landed.
背景the story
把它锻成术语的是人类学：1909 年，范热内普在《过渡礼仪》里把成年礼、婚礼、葬礼 统统拆成三段——脱离、过渡、并入；1964 年，特纳接过中间那段， 把 liminality（阈限）做成了名概念：不再是从前的你，还不是将来的你。
一百年后，这个术语在互联网上二次走红：liminal spaces——空走廊、凌晨加油站、 停业商场的照片美学。它与 kenopsia 是一对：liminal 说的是那个「之间」的状态， kenopsia 说的是站进去时扑面的那口冷清。
Anthropology forged it into a term: in 1909 van Gennep’s Rites of Passage split initiation, weddings and funerals into three movements — separation, transition, incorporation; in 1964 Victor Turner took the middle movement and made liminality a famous concept: no longer who you were, not yet who you will be.
A century on, the word went viral a second time as liminal spaces — the photo aesthetic of empty corridors, 3 a.m. gas stations, dead malls. It pairs with kenopsia: liminal names the in-between state; kenopsia names the chill that meets you when you step inside it.

农事里早有一句：「青黄不接」——陈粮吃完，新麦未熟，正是 liminal 的时间结构。 只是它长在匮乏里，一说出口就是愁；liminal 是中性的，甚至带点出神。 学术译名「阈限」准确而冷，日常里我们其实一直在说：「不上不下」「悬着」。
Chinese farming left the exact time-structure lying around: 青黄不接 — the old grain eaten, the new wheat not yet ripe. But it grew up inside scarcity, and worry comes built in; liminal is neutral, even a little trancelike. The academic rendering 阈限 is precise and cold; in daily speech we have been saying it all along — 不上不下, 悬着.
Airports are liminal by design; nobody is from there, nobody is staying. 自拟例句 our own example, not a quotation The month between the diagnosis and the surgery was pure liminal time — the calendar full, the year on hold. 自拟例句 our own example, not a quotation 词典词（MW／OED），正式与学术写作可用。 注意语域分裂： 论文里它是人类学术语，网上它是一种照片滤镜——写作时想清楚自己站在哪一边。
A dictionary word (MW/OED), good in formal and academic prose. Mind the split register: in a paper it is an anthropological term, online it is a photo filter — know which side you are standing on before you use it.
