"Firstly" and "first" are both used to indicate the beginning of a sequence, but they serve slightly different purposes. "First" is an adjective or adverb that introduces the initial item in a list or order, while "firstly" is an adverb that specifically signals the first point in a series of arguments or statements. In formal writing, "firstly" is often used to structure arguments, but some style guides recommend using "first" instead for simplicity. Additionally, "first" can stand alone, whereas "firstly" typically requires subsequent terms like "secondly" or "thirdly" for consistency. Ultimately, the choice between the two can depend on the context and the desired tone of the writing.
