Etymology
The verb "aggress" is a modern back-formation from the noun "aggression." Its core components trace back to Latin: the prefix ad- ("to, toward") and the verb gradi ("to step, walk"). The literal sense of stepping toward someone evolved into the figurative meaning of initiating an attack or confrontation. This etymological logic is shared with related words like "progress" (stepping forward) and "digress" (stepping away). The modern abstract meaning retains the core concept of moving toward another with hostile intent.
Analysis
Structure: ad (to, toward) + gress (step, walk)
- ad: Latin prefix meaning "to, toward, near." It assimilates to 'ag-' before 'g'.
- gress: From Latin gressus, the past participle stem of gradi meaning "to step, walk."
