dapper [dapper 词源字典]: dapper: [15] Modern English dapper connotes neatness, alertness, and liveliness, but its etymological significance as revealed by distant relatives such as Old High German tapfar ‘heavy’, Old Prussian debīkan ‘large’, and Old Slavic debelu ‘thick’, is ‘heavy’. The notion of ‘weightiness’ spread to ‘firmness, endurance in battle’, and hence ‘courage’ (German tapfer and Dutch dapper both mean ‘brave’). English acquired the word, with an apparently ironical change of meaning, from Middle Dutch or Middle Low German dapper ‘heavy, stout, bold’.

terse: terse: [17] Terse originally meant ‘polished, smooth’ (‘This man … so laboured upon it that he left it smooth and terse’, Helkiah Crooke, Description of the Body of Man 1615). By the 18th century, however, the associated notion of ‘neatness’ had led on to ‘neatly concise’. The word’s present-day negative connotations of ‘brusqueness’ seem to be a comparatively recent development. It was borrowed from tersus, the past participle of Latin tergēre ‘wipe’ (source also of English detergent).
