The word 'wartier' comes from the Old English 'weard' (meaning guard or watch) and the suffix '-ier' (indicating a person who performs a specific action). Thus, 'wartier' refers to a person who guards or watches over something.
Think of someone who is a 'guard' ('weard') — that's why a 'wartier' is a person who watches over or protects.
