expressly

the adverb 'expressly' is built upon the adjective 'express', which entered english from old french 'express' and ultimately from latin 'expressus', the past participle of 'exprimere'. this latin verb is a compound of 'ex-' ('out') and 'premere' ('to press'), literally meaning 'to press out' or 'to squeeze out'. the metaphorical extension from physical pressing to the extraction of clear meaning or intent is evident in the latin usage, where 'expressus' could mean 'clearly stated' or 'distinct'. the english adverbial suffix '-ly' was then appended to this adjective, forming a word that denotes an action performed in a clear, explicit, or deliberate manner, carrying forward the core idea of making something distinct and evident as if pressed out into the open.
