A verb for “turn” appearing in various forms in the Ambidexters Sentence from 1969 (VT49/20-21). It is clearly based on the root √KWER “revolve” (PE17/65), and so probably has that sense as well. If so, this verb might be used both transitively (turn something) and intransitively (turn oneself = revolve).
Conceptual Development: A similar verb ᴱQ. {wir- >>} kere “turn” appeared in Early Qenya Word-lists from the 1920s (PE16/134), likely based on the early root ᴱ√KERE of the same meaning (PE14/65). This early root had a variant ᴱ√ku̯ere [KWER] which Tolkien eventually decided was the normal form of the root.
