Etymology
the word 'decidedly' is built upon the latin verb decidere, which literally meant 'to cut off'. this vivid imagery of cutting away alternatives to reach a conclusion evolved into the abstract sense of 'to determine or settle'. the past participial suffix '-ed' was added to form the adjective 'decided', meaning 'settled' or 'definite'. finally, the old english adverbial suffix '-ly' was appended, transforming it into an adverb that describes an action performed in a clear, unmistakable, and resolute manner. the journey from the physical act of cutting to describing a manner of certainty encapsulates a classic path of semantic evolution.
