Etymology

Origin of synthesis

First recorded in 1580–90; from Latin, from Greek sýnthesis, from syn- syn- + the- (stem of tithénai “to put, place”) + -sis -sis

Explanation

Synthesis is the act of combining elements to form something new. If you describe your bedroom decor as a synthesis of vintage and punk, we'll know you mean a mixture of these two styles. Synthesis can be either concrete or abstract. Scientists use the word to talk about what happens when chemicals combine — think of photosynthesis: the process by which plants synthesize light, carbon dioxide, and water to produce food. If you write a screenplay titled Batman Saves Jane Eyre, then that's synthesis as well (though you may have trouble selling it). Synthesis can also refer to the act of combining ideas.
