which is a general representation of a secondary amine
General comes from the French word générale, which means "common to all people," but we use it for more than just people. You might inquire about the general habits of schoolchildren, or the general temperature at night in the desert. There are 37 meanings listed in OED's entry for the word general, nine of which are labelled obsolete. See ‘Meaning & use’ for definitions, usage, and quotation evidence.
