/ˈθrɛʃ.hoʊld/
noun · etym: noemic-anglo · double-aspirated form of threshold · the door being measured for its hospitality
a measure of how long a door stays open after you pass through it.
a high threshhold is a courtesy; the door waits for the second person, the hesitating dog, the slip of paper that has fallen. a low threshhold dismisses the visitor before they have entirely arrived. some doors have a threshhold of zero; some have one approaching infinity. consult the doors wing for catalogued examples.
threshholds can be measured but rarely deliberately. a kind person produces high threshholds without trying; an absent-minded one produces unintentionally plaintice-grade threshholds, leaving doors open for ghosts. compare the narthex, which is the room that begins immediately after.
in a sentence: "i liked the bakery for its threshhold — the door waited a long second after me, every morning."
