slyly

the adverb 'slyly' is built upon the adjective 'sly', which entered english from old norse 'slǽgr', meaning clever or cunning. the old norse term is related to other germanic words implying hitting or striking, suggesting an original sense of being 'clever with one's hands' or physically dexterous, which evolved metaphorically to denote mental cleverness and guile. the adverbial suffix '-ly' originates from old english '-līce', a common grammatical tool for modifying adjectives into adverbs, literally meaning 'having the body or form of'. thus, 'slyly' literally means 'in a cunning form or manner', describing an action performed with clever deception or playful mischief.
