2. MilitantThe word militant is both an adjective and a noun, and is usually used to mean vigorously active, combative and aggressive, especially in support of a cause, as in 'militant reformers'. It comes from the 15th century Latin "militare" meaning "to serve as a soldier". The related modern concept of the militia as a defensive organization against invaders grew out of the Anglo-Saxon "fyrd".
