pr - temple
The ancient Egyptians used the same word as house for their word for temple. This is because they believed that the temples were the actual physical houses of the diety worshipped there.
The ancient Egyptian word for house is pr (shown below). The hieroglyph pr is a line drawing of a houses walls viewed from above. Because the hieroglyph pr is used both for the word house and for the syllabic sound pr are the same character, the ideogram (also called the pictorial sign, drawn as a short vertical line) is placed below the hieroglyph pr when the meaning is house rather than just the sound. Context indicates whether the word means an ordinary house or a temple.

The ancient Egyptian word house is also used for temples, which are considered to be the personal house of the corresponding deity.
The ancient Egyptians built many of their earliest temples with wooden columns topped with palm leaves. When the Egyptians switched to stone columns they continued to carve palm fronds and leaves into the tops of the columns (see example below).
