This division into two groups is a generalization, however. There are many examples, such as the adjective "español" itself, of adjectives whose lemmas do not end in "-o" but nevertheless take "-a" in the feminine singular as well as "-as" in the feminine plural and thus have four forms: in the case of "español, española, españoles, españolas". There are also adjectives that do not inflect at all (generally words borrowed from other languages, such as the French "beige" (also Hispanicised to "beis")).
