nounfemininei-stemdoorA pluralia tantum (plural only) from earlier *durī, reformulated as an i-stem. Ultimately from Proto-Indo-European *dʰúr-ih₁ (‘double doors’), dual of *dʰúr-o-m (see *durą, ‘door’), from root *dʰwer- (‘door’). Cognate with Old Armenian դուրք (durkʻ, ‘door, entrance, sluice’), Lithuanian dvãras (‘manor’), Old Irish dorus (‘door’), Sanskrit द्वार (dvā́ra, ‘door, gate, passage, entrance; opening, aperture’), and Albanian derë (‘door’). Related to *durą (‘big door, gate’) and *durz (‘door, hatch, flap’).
