Surface Forms

preload singular
preloads plural

Morphology

preload = load (semi-transparent) = pre + load

The structure 'pre-' + 'load' is clear, but the specific engineering sense (a particular applied tension/compression) is technical and may not be obvious to general learners.

Etymology

Preload comes from the prefix pre- 'before' and load 'to put weight or pressure on something', so in mechanics it means giving a part a set pressure or tension before the machine runs to make it fit and work correctly.
