γρήγορα

Etymology: Derived from the adjective 'γρήγορος' (quick, fast), which comes from Ancient Greek 'ἐγρήγορος' (egrḗgoros), meaning 'watchful, alert'. This ultimately derives from the verb 'ἐγείρω' (egeírō), 'to awaken, to rouse'. The semantic shift from 'alert, watchful' to 'quick, fast' reflects how alertness and readiness are associated with speed of action.
