猒# was originally 口 mouth + an obsolete element (肉 flesh and 犬 dog/beast) → the disagreeable sensation of rich/fatty meat pressing upon the intestines → *be satiated*; *become tired/sick of*. 厭 adds 厂, an accretion of uncertain function. For a cognate term in Old Chinese involving rich food, compare 甘.
