Etymology

The word 'wilfully' is built upon the Old English noun will, which denoted desire, intention, or the faculty of volition. This term traces back to the Proto-Germanic weljaną and further to the Proto-Indo-European root welh₁-, meaning "to wish, to will". The suffix -ful was added to form the adjective 'wilful', literally meaning "full of one's own will", thus characterizing someone as determined, obstinate, or intentional. The final adverbial suffix -ly then modifies the adjective to describe the manner of an action. The modern sense of 'wilfully' thus logically evolves from the core idea of acting in a manner characterized by one's own strong desire or intention, often with a connotation of disregarding external rules or advice.
