Conceptual Development: The use of ᴱQ. ya as a relative pronoun dates back to the Early Qenya Grammar (EQG) of the 1920s (PE14/54), but for a period in the 1930s and 40s ᴹQ. ya was used more as a remote demonstrative (Ety/YA; PE23/96-98). See the entry on correlatives for more on this usage as of 1948.
