patently

The adverb 'patently' is built directly upon the adjective 'patent', which entered English in the 14th century from the Latin patēns, meaning 'lying open' or 'exposed'. This Latin root derives from the verb patēre 'to be open', a concept traceable to the Proto-Indo-European root petə-, meaning 'to spread out' or 'to lie flat'. The logical evolution is from the physical sense of being open and accessible to view, to the figurative sense of being clear and undeniable. Thus, 'patently' inherits this core idea, describing an action or state performed in an utterly open, transparent, and therefore obvious manner.

Structure: patent (open, evident) + ly (adverb suffix) - patent: From Latin patent- (stem of patēns), present participle of patēre 'to lie open, be open'. In English, it functions as the core adjective meaning 'open to view, obvious'. - ly: From Old English -līċe, an adverbial suffix forming adverbs from adjectives, indicating manner or degree.
