An adverb derived from akribes ('exact, precise'), appearing in the New Testament in both positive and comparative degrees. In its positive form it describes careful, precise action -- Herod secretly inquires 'accurately' about the star's timing (Matt 2:8), Luke claims to have investigated everything 'carefully' (Luke 1:3), and believers are urged to walk 'carefully' (Eph 5:15). The comparative form (akribesteron) appears in Acts when Priscilla and Aquila explain the Way 'more accurately' to Apollos (18:26) and when opponents seek 'more precise' information about Paul (23:15, 20; 24:22). Spanish neatly distinguishes 'exactamente/diligentemente' from 'mas-exactamente,' and Hindi 'adhik-satikta-se' explicitly marks the comparative increase.
