Tolkien introduced this root early and it retained more or less the same meaning throughout his life. It first appeared as ᴱ√PANA “arrange” in the Qenya Lexicon of the 1910s with derivatives like ᴱQ. pano “series, course, plan, arrangement” and ᴱQ. panya- “plan, arrange, intend, mean” (QL/72). It also had derivatives in the contemporaneous Gnomish Lexicon such as G. pan “arrangement, settlement; place, spot” and G. panta- “set, put, place, arrange, settle” (GL/63).
In The Etymologies of the 1930s it appeared as ᴹ√PAN “place, set, fix in place (especially of wood)”, with derivatives like ᴹQ. panya-/N. penia- “fix, set”, ᴹQ. pano “piece of shaped wood”, and N. pân “plank, fixed board (especially in a floor)” (Ety/PAN). √PAN appeared unglossed in the second version of the Tengwesta Qenderinwa from around 1950 (TQ2: PE18/89) and the root √PAN “arrange, set in order” was mentioned in passing in etymological notes from the late 1960s (PE17/108).
