purely

the word 'purely' is a straightforward english formation from the adjective 'pure' and the ubiquitous adverbial suffix '-ly'. the root 'pure' entered english via old french 'pur' from latin 'purus', which carried the core senses of clean, clear, and unmixed. the latin term is of uncertain deeper origin, though it may be connected to a proto-indo-european root related to fire and purification. the suffix '-ly' has germanic origins, evolving from old english '-līce', which denoted manner or quality. thus, 'purely' literally means 'in a pure manner', a sense which has extended from physical cleanliness to abstract concepts of exclusivity and emphasis.
