  4. bemused

    —The New Yorker Dec 1, 2014
    This word dates from at least 1735, when the word meant "To make utterly confused", a sense it retains to this day. Alexander Pope, in 1705, punned on the "lost in thought" definition by defining bemused as "devoted utterly to the Muses."
  5. feckless
    generally incompetent and ineffectual
    Feckless and irresponsible, Haydon ended up in debtors’ prison four times and, finally, feeling utterly superannuated, committed suicide.
    —Washington Post Oct. 15, 2014

    Feck was the Scottish shortened form of effect and was also used to mean " value" and "vigor."
  6. lackadaisical
    idle or indolent especially in a dreamy way
    The action took place in a sunny, lackadaisical way, with long lags between riders.
    —The Milagro Beanfield War
    This word did not originally mean "idle." lackadaisical meant "vapidly sentimental", the connection being the cry of woe alack the day!, which easily dropped the initial "a." The current meaning of lackadaisical probably comes from the influence of the unrelated lax, "loose, slack."
  7. indolent
    disinclined to work or exertion
    The winged figures in the “Angels’ Tent” are strangely indolent; they recline on hard wooden beds, with umbrellas to shield them from blazing, multicolored suns.
    —New York Times Nov 27, 2014
    From Late Latin indolentem which meant "painless." Modern sense of the English is from the French word indolent, "living easily."
  8. dilatory
    wasting time
    As they press their clients’ interests, these firms specialize in complicated waivers, dilatory obstructions and loopholes in the drafting of both legislation and regulations.
    —Washington Post June 5, 2014

  9. derelict

    To some observers, Twitter was derelict in allowing extremist accounts to flourish.
    —Time Sep 11, 2014
    Latin derelictus "solitary, deserted." From derelinquere, which consists of de- "entirely" and relinquere, "leave behind." The latter word is also at the root of English relinquish.
  10. slipshod
    marked by great carelessness
    Ridiculed for his slipshod handling of the initial investigation, he was pulled off the case and then resigned from the force.
    —Reuters Mar 14, 2014
    This word dates from the 1570s, but its meaning, derived from its component parts, was "wearing slippers or loose shoes" until about 1815, when the word took on the modern meaning of "slovenly" or "careless", an inference about those "shod" in slippers.
  11. beset
    annoy continually or chronically
    The case against him has been beset by problems and delays, with prosecution witnesses refusing to testify or recanting their statements.
    —US News Dec 3, 2014

  12. harried

    “Instead of conveying gravitas, control, a sense of calm and order, speaking too quickly makes you sound harried and amateurish.”
    —Forbes Aug 4, 2014
    Old English hergian "make war, lay waste, ravage, plunder." The sense of "worry, goad, harass", closer to the modern sense of the word, did not arise until the early 15th Century.

  15. discombobulate
    be confusing or perplexing to
    The drum programming was groovy, but often so discombobulated that it seemed right on the edge of being out of rhythm.
    —Washington Post Oct. 9 2014
    Like hornswoggle and lollapalooza, this word is what is known as a fanciful formation- it has no predecessor in another language and was simply created. Discombobulate was originally discombobricate and is first attested in 1834.
