The Spanish word 'paquetazo' comes from combining 'paquete' (meaning 'package') with the augmentative suffix '-azo'. The word 'paquete' itself has an interesting journey, coming from French 'paquet', which in turn derives from Dutch 'pak' meaning 'pack' or 'bundle'. The suffix '-azo' is used in Spanish to indicate something large or intense, so 'paquetazo' literally means 'large package' or 'big bundle'.

This word formation shows how Spanish often uses suffixes to modify the meaning of base words, with '-azo' being a particularly productive suffix for creating augmentatives.

The most obvious related Spanish word is the simpler and more common 'paquete' (package). Other words in this family include 'empaquetado' (packaged), 'empaquetador' (packer), and 'paquetería' (parcel service). All these words share the basic meaning of something being bundled or packed together.

While English 'package' and 'pack' are related to 'paquetazo', they actually come from the same Dutch root 'pak' through different paths. English 'pack' came directly from Dutch, while 'package' developed as a combination of 'pack' with the suffix '-age'. This shows how both Spanish and English independently borrowed and adapted words from Germanic sources to describe the concept of bundling things together.
