Oholos 14:1 - 14:2

הזיז שפניו למטה (the projection from the door frame serving as a shed over the entrance, or a molding projecting from a window-sill serving as a bracket --- the finished side of which faces the ground) – like a tablet/board that projects out from the wall outward and its head is bent to the land to side of the opening. Therefore, its tent combines with the opening and brings the defilement in any amount and it is considered as if it has an opening of a handbreadth, but if the defilement is underneath it, the house is impure, that we see its head bent downward as if it reached the ground and it brings defilement to the side of the house.

וגיזרה – that it faces upward. Its head is bent upward and its tent does not combine with the opening, therefore, it requires an opening of a handbreadth.

וגבלית (a Giblean balcony) – The Tosefta (Tosefta Ohalot, Chapter 14, Halakha 9) explains that it is vessel which sucks from (is girded to the wall on) both sides and left alone (without support) in the middle.

שנים עשר טפחים – for the measurement each נדבך/course of stones or tier/layer is four handbreadths, and a נדבך is a row of the stones of the building.

והעטרות (cornice, molding, wreaths -above the entrance) – stones arranged in a circle that protrude from the wall above from the opening similar to an archway for beauty.

והפתוחים (and the engravings -above the entrance)- that they make from stone on the opening or on the window for beauty, and sometimes they protrude from the window or from the opening a handbreadth or more.

זיז שעל גבי הפתח וכו' – here we are speaking where the opening is concealed. And because of this, we require that the projection will have an opening of a handbreadth. And this is implied in the Tosefta (see Tosefta Ohalot, Chapter 14, Halakha 9).

ושעל גבי החלון רום אצבעיים – that is to say, whether a window whose measure is a height of two fingerbreadths, such as the remnants of the light-hole (i.e., opening in the wall from the start – see Tractate Ohalot, Chapter 13, Mishnah 1) or whether its measurement is as large as the hole made with the [large carpenter’s] borer/drill, as for example, that makes the light-hole at the outset, the projection that on top of both of this is whatever the amount.

ורבי יוסי אומר מלואו (only if its height is of equal measure/of full capacity) – a window whose measure is a height of two fingerbreadths, its projection it’s measure is with two fingerbreadths. But a window whose measurement is as large as the hole made by a borer/drill, its projection we also estimate/assess to be as large as the hole made by a borer/drill. But the Halakha is not according to Rabbi Yossi.
