The word 'vegetal' originates from the Latin verb vegetare, meaning 'to enliven, animate, or invigorate,' which itself is derived from vegēre, 'to be lively or active.' This root is connected to the Proto-Indo-European base weg-, meaning 'to be strong or lively.' Interestingly, this vibrant, active sense in Latin became semantically narrowed when applied to plant life. In medieval scientific Latin, vegetabilis described things capable of growth and life, as opposed to inanimate minerals, leading to the modern association with plants. Thus, 'vegetal' retains the core idea of organic life and growth, but specifically that which is characteristic of the plant kingdom, distinct from animal ('animalis,' from anima, 'breath, soul') or human consciousness.
