ᴱ√PERE root. “*endure”
An unglossed root in the Qenya Lexicon of the 1910s Tolkien said was similar in meaning to ᴱ√PENE “*through” (QL/73). Some of its derivatives had similar meanings like ᴱQ. perma “passage; pass, aperture”, but most of its derivatives had to do with enduring and endurance. In Tolkien’s later writings the sense “endure” was generally assigned to the root ᴹ√BOR(ON).
