Changes or converts something completely in form, appearance, nature, or character. Can also function as a noun referring to mathematical operations that change coordinates or data.
From Latin transformare, combining trans- 'across, beyond' and formare 'to form.' The word entered English in the 14th century through Old French transformer, initially used in religious contexts to describe spiritual change, later expanding to physical and mathematical transformations.
In mathematics, transforms like the Fourier transform are among humanity's most powerful tools, converting complex waveforms into simple frequency components - it's how your phone recognizes your voice and how medical imaging reveals the inside of your body. The word captures both magical metamorphosis and precise scientific process, bridging poetry and engineering.
