A word appearing as ᴱQ. tarwa “garden, enclosure” in the Qenya Lexicon of the 1910s under the early root ᴱ√TAÐA (QL/87). The Qenya Phonology from this period had [unglossed] tarva, the form in the Cortirion dialect where rw > rv (PE12/24). The Gnomish Lexicon of the 1910s had ᴱQ. tarwa as a cognate to G. taru “horned” but both these words were deleted (GL/69).

Neo-Quenya: I personally would retain ᴺQ. tarwa “garden, enclosure” for purposes of Neo-Quenya based on a Neo-Root ᴺ√TAD “enclosure”. For example, Helge Fauskanger used this word in his Neo-Quenya New Testament (NQNT). If, however, you find it dubious you might instead use the neologism ᴺQ. santa for “garden”, inspired by S. sant from the late 1960s (VT42/20).
