The word 'tangibly' is built upon the Latin root tangere, meaning "to touch". This root is also the source of words like 'tangible', 'tactile', and 'contact'. The suffix '-ible' (from Latin -ibilis) was added to form the adjective 'tangible', meaning "able to be touched" or "perceptible by touch". Finally, the adverbial suffix '-ly' (from Old English -lice, via Germanic) was appended, transforming the adjective into an adverb that describes the manner of being perceptible to the senses. Thus, the literal meaning "in a manner able to be touched" evolved into the modern abstract sense of being real, concrete, and clearly demonstrable.
