甘 is a bound form (b.f.) — it cannot stand alone as a word and appears only as a morpheme in compounds. Its main senses are 'sweet' or 'pleasant' in taste or quality (甘甜, 甘美), 'willing' or 'voluntary' (甘愿, 甘心), and it also serves as the abbreviated name for Gansu Province (甘肃). In formal or literary Chinese, it can convey satisfaction or acceptance of a situation.
