Hi Joe,

Well, to woo and to court can be used as synonyms, I guess, but yes, to woo would be slightly more explicit.

The leaves and the green grass are nature; in that time they are (expected to be) present in any location on solid land. On the other hand, life with a nix, a neck(?) was not natural. It also wasn't like being tempted to enter the splendid hills/halls of the fay folk: The home of a nix was usually supposed to be a miserable place to live for a human, and a nix is an ugly, mean creature that will cause ships to sink and vanish. Thus, by parting from the grass and the leaves, she gives up normal life for the sake of her children. For seven years she has held hope to escape her watery prison and return to her own world on land, but now she gives in to the nix' machinations and willingly goes back to him, giving up her hope so her children may not come to harm.

Bye,
