The Spanish verb 'conseguir' (meaning 'to achieve' or 'to obtain') comes from the Latin verb 'consequi', which meant 'to follow through' or 'to achieve'. The Latin 'consequi' itself was formed by combining two elements: the prefix 'con-' meaning 'together' or 'with', and the verb 'sequi' meaning 'to follow'. When these elements merged, the literal meaning was something like 'to follow together/through', which evolved to mean 'to achieve' or 'obtain' as the idea of following something through to completion became associated with achieving a goal.

Several common Spanish words share this Latin root 'sequi' (to follow). For example, 'seguir' means 'to follow' or 'to continue', and is a simpler and more frequently used verb. The word 'siguiente' meaning 'next' or 'following' is also related. You can see how all these words maintain the basic concept of following or coming after something.

Many English words are related to 'conseguir' through the Latin roots 'con-' and 'sequi'. Some common examples include 'sequence' (a following of one thing after another), 'consequence' (something that follows as a result), and 'subsequent' (following after). The word 'sequel' (something that follows) is another clear example. All these words share the basic meaning of following or coming after, though each has developed its own specific usage.
