The Spanish word 'picado' (meaning 'pricked' or 'chopped') comes from the verb 'picar' ('to prick' or 'to sting'), which traces back to the Latin verb 'picare' meaning 'to peck' or 'pierce'. The Latin 'picare' itself derives from 'picus', meaning 'woodpecker' - a bird known for pecking and making holes in trees. This etymology shows how the meaning evolved from the action of a woodpecker's pecking to the more general concepts of pricking, piercing, or chopping in Spanish.

Some common related Spanish words include the verb 'picar' (to prick, sting, or chop), 'pico' (beak or peak), 'picadura' (sting or bite), and 'picante' (spicy/hot). All these words share the common thread of something sharp or pointed, or an action involving piercing or pricking - similar to how a woodpecker uses its beak.

While English 'pick' (as in to peck or pierce) and 'peck' themselves come from different Germanic roots, English has borrowed some related words from the same Latin source, such as 'pike' (a sharp pointed weapon) and 'peak' (originally referring to a pointed hill). The word 'piccolo' (a small flute) also comes from the same Latin root, originally referring to a small, pointed instrument.
