Q. hala n. “cast shadow” (Category: Shade, Shadow)
A Quenya word meaning “a cast shadow” appearing in two forms, hala and (archaic) †ixal, both cognates to S. esgal and derived from the root √SKAL “cover, veil, cloak, conceal” (PE17/184). The form hala is the normal development from primitive ✶skalā where the initial sk eventually became h, whereas ixal shows a vowel i developing before syllabic ṣ and then the surviving sk undergoing metathesis to ks (x).
Neo-Quenya: Given that primitive ✶skalā is actually “the action or effect of overshadowing”, I think hala can mean both “(cast) shadow” and “*shade” as in a shaded region beneath a screen of leaves or something similar. For the screen itself I’d use fanwa.
