The Moon
YEAR - YAREACH

Hebrew YAREACH "Moon"
Latvian IE-RADZIS, IERAGS "the horned one"
 

The simple contraposition of current terms for a given concept in any two languages does not yet say anything meaningful about their origin since these terms may go back to ancient alternatives for "naming" an object.

The moon is a very good example for this principle.

If the "moon" did not yet have name, how would one name it?

1. For its color - yellow - Semitic YARQANU ia-ar-qa-ni Latvian DZELTGANU (note Hebrew YARQANU also means "green" - Latvian ZALGANU)

2. For the fact that it changes shape and location - this is Latvian MENESS or MENESIS, to which compare MIJA, MAINA-, MAINESIS "change, the changing one" nearly correct as PIE *me (2) "measure".

3. For what you imagine it to be - perhaps a "stone" in heaven - Latvian AK-MENIS

4. For its crescent, horned shape - which is what we use symbollically to represent the Moon as a heavenly body - Latvian RAG- "horn" or IERAG- or IERADZ- "horned" - this looks like YAREACH

5. For its light, alleged PIE root *leuk-sna (this would be Latvian (IE)LAUK- "field, time. light area. Lichtung", and Baltic Old Prussian LAUXNOS "stars, i.e. of the heavens") which then led to forms such as "luna"

6. For the fact that it is "outside" in the "air" - Latvian ARA, ARUMA, ARUMINA whence perhaps the Northwest Semitic forms for "moon" cited by Sivan:

ia-ri-chi-ma-nu    ya-ar-chi    a-ar-hu-um-ma    E-ar-[h]a

This would be the comparable to the Zoroastric Ahriman - showing the age-old battle between the reverence of the Moon and that of the Sun, Ahura Mazda = RA.MESH, SHA.MESH.
