Did you know?

While evidence dates bumptious to the beginning of the 19th century, the word was uncommon enough decades later that Edward Bulwer-Lytton included the following in his 1850 My Novel: "'She holds her head higher, I think,' said the landlord, smiling. 'She was always—not exactly proud like, but what I calls Bumptious.' 'I never heard that word before,' said the parson, laying down his knife and fork. 'Bumptious indeed, though I believe it is not in the dictionary, has crept into familiar parlance, especially amongst young folks at school and college.'" The word is, of course, now in "the dictionary"; ours notes that it comes from the noun bump and the suffix -tious, echoing other disapproving modifiers including captious ("fault-finding") and fractious ("troublemaking").
