The word "more battleful" is derived from two separate linguistic components: "more" and "battleful".
1. "More" comes from the Old English word "māra", which means "greater" or "additional". It has remained relatively unchanged in its meaning over time and is used to indicate a higher degree or quantity.
2. "Battleful" is a combination of "battle" and the suffix "-ful". "Battle" originates from the Old English word "batel" or "bætl", which referred to a fight or combat. "-ful" is a suffix used to form adjectives and means "full of" or "characterized by". So, by adding "-ful" to "battle", the word "battleful" indicates being full of battles or characterized by a battle-like nature.
