受宠 is a separable verb (离合词) meaning 'to receive favor or special treatment from a superior or authority figure'. It is most commonly encountered in the idiom 受宠若惊 ('overwhelmed by unexpected favor', literally 'receive favor so much that one is startled'). In formal or literary contexts it can be split — e.g. 受了一次宠 ('received a favor once') — but the unsplit form is much more frequent. The 'favor' is typically a genuine expression of kindness or privilege from someone in a higher position, not a general 'like' or 'preference'.
