The stem contains the nominal’s basic meaning. This includes: gender, number, and case.
A stem + an ending creates a complete word. Example:
simha + h → simhah
the lion
simha + sya → simhasya
of the lion
simha + aih → simhaih
by the lions
Three genders
Masculine → simho (lion, masculine)
Feminine → simhaa (lion, female)
Neuter → vanam (forest)
Nominal stems use any gender, but noun stems generally have a fixed gender (even if they don’t physically have a gender)
Yoga - yoga (masc.)
Niiti - wise conduct (fem.)
Nirvaana - nirvana (neut.)
