Relating to or resembling the heart shape, or in some technical contexts, relating to cords or cordage.
From Latin cor meaning 'heart,' combined with the suffix -al meaning 'relating to.' This adjective developed to describe things shaped like a heart.
The heart-shape connection comes from medieval symbolism where the actual human heart was believed to have a point at the bottom and curves at the top—exactly like the ♥ symbol we still use today.
