Morphology

injection = inject (transparent) = inject + ion

Direct noun formation from the verb 'inject' with the productive suffix '-ion'; the meaning 'act of injecting' is straightforward.

Etymology

Injection comes from the parts in- ('into') and ject ('throw'), the same ject you see in eject and project, which gives the image of 'throwing into'. So injection can mean forcefully putting a liquid or fuel 'into' a machine or system, which fits modern uses like fuel or dye injection.
