熙怡（上虛飢反字統云熈和也考聲云美也從灬[(厂-一)*臣*巳]聲也[(厂-一)*臣*巳]音同上灬必遙反有作凞熈二形皆非下以之反考聲怡喜悅也說文云和也從心台聲台音以之反）。

熙怡 (Joyful and cheerful: the upper character has the fanqie 虛飢; the Zhitong says that 熈 means harmonious; the Kaosheng says it means beautiful; it is formed from 灬 with the phonetic [(厂-一)*臣*巳]; [(厂-一)*臣*巳] has the same pronunciation as above; 灬 has the fanqie 必遙; the two forms 凞 and 熈 are both non-standard. The lower character has the fanqie 以之; the Kaosheng says that 怡 means glad and delighted; the Shuowen says it means harmonious; it is formed from 心 with the phonetic 台; 台 has the fanqie 以之).
