youthful and endearing; rosy-cheeked and sweet
A yojijukugo describing a young person, especially a girl, with a fresh, innocent, and charming appearance. Literary and somewhat old-fashioned; not used in everyday conversation.
Everyone was captivated by her youthful and endearing smile.
その少女は紅顔可憐という言葉がぴったりの愛らしさだった。
The girl was so lovely that the phrase 'rosy-cheeked and sweet' suited her perfectly.
可憐 alone means 'pretty' or 'lovely' and is more common. 紅顔可憐 adds the nuance of youthful, rosy-cheeked beauty.
紅顔 means 'rosy cheeks' or 'youthful face' and is a literary term. Combined with 可憐, it emphasizes a sweet, innocent charm.
A yojijukugo composed of 紅顔 (rosy cheeks, youthful face) and 可憐 (pretty, lovely). The exact origin is uncertain, but it follows classical Chinese-influenced literary patterns.
