Person radical on the left - the indexing semantic. The original
倾 meant a person leaning or tilting; from a tilted body came the broader meanings 'lean, incline, pour out, tend toward'. The
亻 anchors
倾 in the human-action family alongside
倒 (fall over),
偏 (slanted),
侧 (sideways) - all body-position verbs.
