I learned that in the real world Amlonde is a given name of South African origin (I cannot be more precise on linguistic background or meaning). But the word looks suspiciously like a word from Tolkien's Elvish languages. I looked it up in Helmut Pesch's dictionary, but it is not attested there.
So my question is: Can this word be analysed in Sindarin and/or Quenya, and what would it mean than?
EDIT: Some clarifications on possible answers: I am not looking for arbitrary suggestions of a meaning. Any analysis shall be based on published material on Sindarin and Quenya, including diachronic development and lesser known dialects. An answer that the word is in fact impossible in Quenya or Sindarin with some argument why this is the case is also a legitimate answer.
