Others have responded, but I will add my 2 cents.
The Latin "Venus" is a nominative case in the _third_ declension. The
"-us" suffix is usually a second declension masculine noun, but not in
In order to form other words from a nominative root one needs to
discover the "stem" of the word. This is best done by removing the
suffix from the _genitive_ case, not the nominative case. The reason
for this is that some words, like "Venus," have an irregular nominative
form. Simply removing what one assumes to be the ending and adding
another of the proper form will not give the correct stem and ending
Our case in point is the nominative "Venus," which has the genitive
"Veneris." The suffix of the genitive is "-is," so the stem becomes
"Vener-" to which appropriate endings may be added.
The same is the case for the irregular noun "Asclepias" whose genitive
case is "Asclepiadis." This is why the name of the family, of which
Asclepias is the type genus, is "Asclepiadaceae" and not "Asclepiaceae"
or some other malformation.
