Morphology

first + strike

The meaning 'an initial or pre-emptive attack' is directly derived from combining 'first' (preceding others in time) with 'strike' (an offensive action), so a learner who knows both words will infer it refers to the initial/primary attack. Although the term carries domain-specific nuances (military/cyber pre-emption), the basic compositional sense is transparent and common across languages.

Etymology

First strike gives a simple image: the first quick strike is used to stop a danger before it can act or 'hit back'. That's why people use it for pre-emptive attacks in war, cyber, or other areas to stop a threat that is 'about to happen'.
