Query: An Etymological Dictionary of Astronomy and Astrophysics:
  English-French-Persian   This online dictionary presents the definition of classical as well as
advanced concepts of modern astronomy. Moreover, each English entry is
accompanied by its French and Persian equivalents. The dictionary is intended
to be helpful to professional as well as amateur astronomers. As a notable
particularity, it also provides a detailed etymology of English and Persian
terms. The etymological material contained in this work may interest linguists,
in particular those concerned with the evolution of Indo-European languages,
especially with that of their Iranian branch. Apart from educational and
outreach objectives in the field of astronomy, one of the main aims of this
work is to contribute to the Persian language by creating a comprehensive
dictionary of astronomy and astrophysics.
