- A tendency, especially in thought or feeling, contrary to what seems the strongest: “As she talks nostalgically of her days of glory … a poignant undertow emerges” ( Tina Brown )
(third-person singular simple present undertows, present participle undertowing, simple past and past participle undertowed)
From under- +"Ž tow.
