裕 is a bound form (b.f.) meaning 'abundant' or 'affluent'. It does not stand alone as a word but appears as a morpheme in compound adjectives and nouns, such as 富裕 (wealthy), 充裕 (abundant), 宽裕 (well-off), and 丰裕 (plentiful). You'll encounter it most often in formal or written Chinese describing economic conditions or resource availability.
