Is it a term for one's mother or grandmother in some places? It feels to me like it is, but I did a quick online search and it doesn't seem so. I like
Ama's symmetry and simplicity; it almost seems like it should be lacking something, but somehow it isn't. As you mentioned
Ama Lia, it would make an oddly unexpected, and certainly pleasant, nickname for
Amalia. I think I like it.
Whenever I have name dreams, the baby is always given the same name, Romilly, unsurprising given my deep and unwavering love for it :)
