In every location or everywhere; all over the place or in all parts of an area.
Compound of 'every' and 'place' (from Latin 'platea', street, broadened to mean location). The formation parallels 'everywhere' with an alternative structure popular in American dialect.
English has multiple ways to say 'everywhere'—everyplace, everywhere, and every place—and Americans tend to prefer 'everyplace' while British English favors 'everywhere', a classic dialect divide!
