The Quenya words for the color black are morë, and morna (dark, gloomy, blackness) or morqua (a non-LOTR form of morna).

The Sindarin word for the color black is morn.

Sand, in J.R.R. Tolkien's words

The Quenya word for sand is litsë.

The Sindarin word for sand is lith.

Sand, in my words

sarn : sand

The Illunse word for sand is sarn. In Sindarin sarn translates to small stone or pebble. In Welsh sarn tranlates to causeway or litter. Sarn can be an British last name. Sarn is the name of cities in Switzerland and Wales.

This word is a mixture of the Old English word for sand which is sand (same as Modern English), and the Latin word for sand which is harena or arena.

River, in J.R.R. Tolkien's words

The Quenya word for river is sírë (river, stream).

The Sindarin words for river are sîr (river) and duin (long and large river).

Stone, in J.R.R. Tolkien's words

The Quenya word for stone is ondo (stone as a material, rock) or sar (pebble, stone) or sarna (of stone).

The Sindarin word for stone is sarn (stone as a material, pebble) or gond (stone, rock).

I learned by something interesting looking up this word -- Gondor, the Middle-Earth kingdom where you'd find the city of Minas Tirith, means "Land of Stone" in Sindarin.

Glass, in J.R.R. Tolkien's words

The Quenya word for glass is hyellë.

The Sindarin word for glass is heledh.

I think that these are the elven words for glass as a substance, not glass as a drinking cup or a looking glass.

Glass, in my words

glist : glass

The Illunse word for glass (material) is glist. In English glist (taken from glisten) can mean glimmer or mica. Glist is a last name.

This word is a mixture of the Old English word for glass which is glæs, and the Latin word for glass which is vitrum.

Blood, in J.R.R. Tolkien's words

The Quenya words for blood are sercë and yár.

The Sindarin words for blood are sereg and agar.

Each of these elven languages have two words for blood, and I'm not sure what the difference is between the words. The first words seem more common. Perhaps the second words are more like blood in battle or gore.

Blood, in my words

solg : blood

The Illunse word for blood is solg. Solg is the name of a city in Germany.

This word is a mashup of the Latin word for blood which is sanguis and the Old English word for blood which is blod or blód. My Illunse word doesn't really look like either word.

Bronze, in my words

raes : bronze

The Illunse word for bronze (metal alloy) is raes. In Old English rǽs traslates to a race, rush, leap or jump.

This word is a mixture of the Old English word for bronze which is braes, and the Latin word for bronze, which is aes or aeris.

Bronze is a metal alloy. Bronze is mostly copper, with some tin added (usually between 5% and 20% tin). Bronze was the first alloy that was used by humans.

Tin, in J.R.R. Tolkien's words

The Quenya word for tin (metal) is latúcen.

If there's a Sindarin word for tin, I didn't find it.

Lead, in J.R.R. Tolkien's words

The Quenya word for lead (metal) is canu.

I couldn't find a Sindarin word for lead. Maybe there isn't such a word.
