the word 'synthetically' is built upon the greek root 'synthetos', the past participle of 'syntithenai', meaning 'to put together'. this verb itself is a compound of 'syn-' (together) and 'tithenai' (to put, to place). the greek '-ikos' suffix was adopted into latin as '-icus', entering english via old french as '-ic' to form adjectives like 'synthetic', meaning 'pertaining to putting together'. the english adverb-forming suffix '-ally' was then appended. the core concept of 'putting together' evolved from a general physical sense to the specific modern meanings of constructing complex ideas logically or producing compounds via chemical synthesis.

Structure: synthet (put together) + ic (adjective suffix) + ally (adverb suffix) synthet (from greek 'synthetos', meaning 'put together, compounded'); ic (from greek '-ikos', a suffix forming adjectives meaning 'of or pertaining to'); ally (from latin '-aliter' via old french '-elment', a suffix forming adverbs from adjectives)
