verb lucubrate comes from the Latin verb elucubrare, a default of lucubrare. This word is derived from lucubrun ( otherwise small of any kind for night 41 alubrarse; formed with lux 40 root; light ) and the instrumental suffix - brum.It elucubrare was in principle work watching in the night to the light of a lamp, where happens to mean striving with vigils in a work or an argument. There goes too finally to speculate at length about something in some conditions of Vigil, effort and fatigue, as a consequence, wander or think much and too unsubstantiated. Lucubrate therefore belongs to la familia léxica de lux and thus share with words such as light, fire, light, moon, illuminate, illustrate, etc.
