The Spanish word 'soga', meaning 'rope', comes from Late Latin 'soca', which meant both 'rope' and 'tree stump'. This is a relatively straightforward evolution where the meaning narrowed to specifically refer to rope, while the pronunciation shifted from 'soca' to 'soga'.

There aren't many common Spanish words that are clearly related to 'soga', as it's a relatively basic term itself. The word is commonly used in Spanish when referring to ropes, particularly thick ropes or cords.

While there aren't direct cognates in English that come from the same Late Latin root 'soca', English speakers might find it helpful to remember that 'soga' sounds somewhat similar to the word 'soak', though they're not actually related. You might imagine a rope getting soaked to help remember the connection, even though it's just a memory aid rather than a true etymology.
