history
颐 is a classical character meaning to nourish or nurture. It appears in the idiom 颐养天年 (yí yǎng tiānnián, to enjoy one's remaining years) and in 颐和园 — the Summer Palace — whose name means 'garden for cultivating harmony and good health.'
页 on the right is the indexing radical, a head-and-neck silhouette. It locks 颐 into the face-and-head family with 颊 (cheek) and 颜 (face), pinpointing the lower jaw region the word names.
臣 on the left is a graphic residue rather than its minister meaning here; its boxed shape preserves the older outline of a jaw and chin. It contributes the lower-face profile that gives 颐 its sense of cheek and jowl.
