Nomenclature dictionary (updated)

An informal English-to-Latin/Greek dictionary to assist in the systematic naming of imaginary taxa.

For the sake of simplicity, only the masculine form of adjectives is listed here.
In most cases the feminine and neuter forms of adjectives are found by replacing the -us termination with -a and -um, respectively (e.g. minutus, minuta, minutum). Likewise, the feminine and neuter forms of adjectives ending with -er are found by adding -a and -um, respectively (e.g. fructifer, fructifera, fructiferum).
The neuter form of adjectives ending with -is is found by replacing the -is termination with -e (e.g. imperialis, imperialis, imperiale).
The feminine form of nouns ending with -tor is found by replacing the -tor termination with -trix and -um, respectively (e.g. piscator, piscatrix).

Needless to say, it’s still incomplete, but It will be updated regularly.
