Morphology
The phrase combines 'swap' (to exchange) and 'space' (an area or area reserved), so a learner who knows both words can infer it denotes an area used for swapping. However, the specific technical sense — that this is disk space reserved for virtual memory and page-swapping — requires domain knowledge and is not fully predictable from the constituents alone.
Etymology
Swap space comes from the idea of swap, meaning 'to exchange', and space, meaning an area on the disk. Imagine your computer's fast memory as a small desk and the disk area as a box where you put extra papers; when the desk is full you move papers to the box and later bring them back. That's why swap space means the disk area used as 'virtual memory' when physical memory is full.
