A four-dimensional framework that joins space and time where events happen

is the shorter term without the extra noun

Surface Forms

spacetime singular
spacetimes plural

Morphology

spacetime = space + time (semi-transparent) = space + time

The compound clearly signals a combination of 'space' and 'time', but the precise technical meaning as a four-dimensional physical continuum is specialized and may not be fully derivable by a general B1 learner.

Etymology

The word spacetime joins the simple words space 'the place around us' and time 'when things happen', making one word used by scientists. This helps you remember that, in modern physics, space and time are joined into one 'fabric', so spacetime is the single 'stage' where all events happen.
