Morphology

in + vacuo

The phrase literally combines the preposition 'in' with 'vacuo' (meaning 'in isolation' or 'in emptiness'), so its meaning 'in a vacuum / in isolation' is directly derivable from the constituents. Although 'vacuo' is a Latin-derived technical term, its root matches English cognates (vacuum, vacant) and the composition follows a regular spatial/abstract pattern, making the expression transparent to a learner who knows both parts.

Etymology

In vacuo comes from Latin words in and vacuo, meaning 'in empty space'. Picture an object inside a glass jar where the air has been sucked out so nothing can touch it. That's why scientists use the phrase to mean 'in a vacuum' with no air or gas.
