A verb for “flow” in The Etymologies of the 1930s under the root ᴹ√SIR of the same meaning (Ety/SIR). It may have appeared later in its present-tense form síra in the Quenya Verbal System (QVS) from 1948 as part of the sentence [ᴹQ.] númen Endorello isse sí Vaia síra “westward of Middle-earth where now Ocean flows” (PE22/126). However, it is possible that síra was intended to be present of the verb [ᴹQ.] sirya- “flow” from elsewhere in QVS; see that entry for discussion.
Conceptual Development: The Qenya Lexicon of the 1910s had ᴱQ. siri- “flow” under the early root ᴱ√SIŘI [SIÐI] (QL/84). See also the later verb Q. sirya-.
