Tar-Hostamir was the 21st ruler of Númenor, also known as Ar-Zimrathôn. The second element of his name is probably mírë “jewel”, and the initial element may be ᴹQ. hosta “a large number”, so that the name means: “*Many Jewels”. Andreas Moehn instead suggested (EotAL/ZIM’R) that the initial element may be a form of the verb hosta- “to gather”, so meaning: “*Gather Jewels”.
