Usage notes

• Many dictionaries mention feminine gender, while Stephanus Ximenez' dictionary mentions masculine gender and while Englishmen mention neuter gender.
  • The neuter gender could be a guess based on Greek ῥομβοειδὲς σχῆμα n (rhomboeidès skhêma). However, the Greek neuter form has a short e in the nominative singular ending and not a long e. Also the plural form rhomboides can be found which does not fit to a neuter noun, but to a masculine or feminine noun.
  • Masculine gender does fit with Latin rhombus m, Greek ῥόμβος m (rhómbos) and also German Rhombus m and Rhomboides m which also were declined like Latin words.
