Sense: verb/1
Redden is the most general verb for becoming red — it can describe faces, skin, leaves, food, or any object changing colour. Blush is limited to the face and specifically means reddening from embarrassment, shyness, or modesty. Flush can describe the face reddening from a wider range of emotions (anger, pride, excitement) or from physical causes like fever or exercise. Turn red is the most common everyday phrase and can replace redden in almost all contexts, though it is less formal. For example: 'Her cheeks reddened when she walked into the cold wind' (neutral observation) versus 'She blushed when he complimented her haircut' (embarrassment) versus 'His face flushed with anger as he stood up from the table' (strong emotion).

Etymology
From Old English 'rēad' (red) plus the verb-forming suffix '-ian', making it a denominal verb meaning 'to become or make red'. The word is related to the same Germanic root as German 'rot' and Dutch 'rood' (red), and is distantly connected to Latin 'ruber' and Greek 'erythros' through the shared Indo-European root for red.
