marked by extreme or excessive care over detail
Every detail, from the pearl pin in the black satin cravat to the lavender spats over the varnished shoes, spoke of the meticulous care in dress for which he was famous — Conan Doyle
meticulously adv
meticulousness noun
Latin meticulosus timid, from metus fear. Although the earlier uses of meticulous were derogatory, it now usually indicates approval. Its original sense (from the 17th cent.) was ‘fearful, timid’, but this sense has long been obsolete. In the 19th cent. it came to mean ‘overconcerned with details, fussy’. Now it usually signifies ‘commendably precise’
