This adverb describes action done with careful attention and thoroughness. In Luke 15:8, the woman searching for her lost coin does so carefully, sweeping diligently through her house. The multilingual evidence (Spanish cuidadosamente, French soigneusement) consistently emphasizes the deliberate, attentive quality of the action. Classical Greek used this word for medical precision and philosophical exactness, showing how careful observation was valued in both practical and intellectual pursuits.
