I learned in a bio class about the singular and plural forms of genus
and species, and how we use the adjective form in common usage without
realizing it.
So I created the following table:

sing: genus, species
pl: genera, species
adj1: generic, specific
adj2: general, special
verb2: generalize, specialize
verb1: ?, specify

What goes in the ? slot? Why is there no "genify" or "generify" or
some such word?

Was "generalize" created to fill that hole? Then someone screwed it up
again by inventing "specialize?"

Hasta la pasta,

I tried the real world once; didn't really care for it.
