IPA: /ˈhɒtspɜːr/
KK: /hɑtspɜr/
A person who acts quickly and without thinking, often in a reckless or impulsive way.
He was known as a hotspur, always rushing into situations without considering the consequences.
Hotspur → The word 'hotspur' is derived from the Old English 'hōt' (meaning hot or fiery) and 'spear' (from Old English 'spear', meaning a weapon). The term originally referred to a fiery or impetuous person, particularly one who is eager to fight or act quickly, much like a spear is a weapon used in battle.
Think of someone who is 'fiery' ('hōt') and quick to act, like a 'spear' — that's why 'hotspur' describes a person who is eager and impetuous.
