A DOOR is a portal which swings open and closed on hinges.
The Amer. Heritage Dictionary’s Indo-European “root”, dhwer (door, doorway), treats DOOR figuratively.
It therefore counts as extended cognates those words that mean out-of-doors, like FOREIGN and FOREST. The sound and sense of Semiticly-challenged etymology can be unhinging.
Old English dor, Greek thura and Persian dar do mean a real door… a panel that swings open or closed.
Edenic דור Dalet-Vav-Resh DOOR is defined by Harkavy as “to turn, to circle”… with extensions meaning a circle or ball ( כדור Ka
DOOR – Isaiah 29:3), and a circle of time or a generation (דור DOAR – Psalms 77:9). You may see our Dalet-Vav-Resh here as “rim of a wheel” at
TIRE. We turn our etymology open wider with the other dentals and R. תור TOAR is a circlet or turn; תור TOAR is a plait or circlet in Songs 1:10; עטרה [A]
DTaRaH is a (circular) crown (Songs 3:11); עטר [A]DTaR is to surround - see
TIARA. For straight dental-liquid related opposites , like DTOOR, a row or tier – see
TIER. דלת DeLeT (door) does begin with a dental-liquid, but it refers to a DELTOID, triangular tent flap – see DELTA. A river DELTA is about portals, but a DOOR, etymologically, is about swinging on hinges, not DOORWAYS. דלת DeLeT is used metaphorically, like the “doors”of a womb in Job 41:6. The literal, דור Dalet-Vav-Resh DOOR is best seen in a different דלת DeLeT verse: “a door turneth upon its hinges” – Proverbs 26:14. The word for “hinge” is another dental-R, ציר TSeeYR. The word also means to revolve.
