indeclinable (adverb)
Analysis. sam + kacca, 'with care/carefulness'; the prefix saṁ- (together, completely) intensifies kacca (carefulness, heed), forming an adverbial expression of thoroughness and respect.
Etymology. From saṁ- (together, completely; cognate with English 'same', Latin similis) + kacca (care, heed), a root meaning 'to be careful or attentive'. The compound sense 'with complete care' develops into the adverbial sense of doing something with full attention and respect, characteristic of monastic conduct.
