gwadh-

verb. to dwell

A verb appearing as G. gwadh- “dwell” in the Gnomish Lexicon of the 1910s with a (deleted) primitive form gu̯ađ (GL/46), likely an allusion to the early root ᴱ√ẆAÐA from the contemporaneous Qenya Lexicon (QL/102). In that document, Tolkien gave the Gnomish form as {gwath- >>} gwar-, however, which might align with the deleted primitive form ᴱ✶gu̯ara- “dwell” from the Gnomish Lexicon (GL/38).

mar(o)n

adjective. ripe

marol

noun. sand

A noun with variants marol and mara in the Gnomish Lexicon of the 1910s glossed “sand”, probably a derivative of the root ᴱ√MARA (GL/56); see the entry on the root for further discussion. In later writings, Tolkien used N. lith for “sand”.

polodrin

adjective. mighty

A word appearing as G. polodrin “mighty” in the Gnomish Lexicon of the 1910s, an adjective form of G. polod “power, might, authority” (GL/64). It had an archaic variant {poldurin >>} †polurin or polorin which was sometimes used as a sobriquet for Tulcus.

Neo-Sindarin: Since ᴹ√POL(OD) still had to do with “strength” in Tolkien’s later writings, I’d adapt this word as ᴺS. polodhren “mighty, ✱powerful” for purposes of Neo-Sindarin using the later Sindarin adjective -ren. Given the meanings of its base noun (including authority), I’d assume this adjective has a connotation of political power. I’d constrast it with S. belaith which I’d use for “mighty” in general (independent of authority).
