.pdfconcealed in a shoulder holster. By the 1920s it had become a metaphor for any surprise advantage or leverage.
ace it
Accomplish something with success, as in I'm sure he'll ace it when he takes that bar exam. The verb ace originated in tennis with the meaning "to hit an unreturnable serve against an opponent." The idiom ace it, however, originated as student slang for getting an "A" on an exam or in a course but soon was extended to other successful accomplishments. [Slang; mid-1900s]
ace out
1. Get the better of, defeat, as in Our team is bound to ace them out, or Those calculus problems aced me out again. [Slang; mid-1900s] 2. Take advantage of or cheat someone, as in John thought they were trying to ace him out of his promised promotion. [Slang; c. 1920]
Achilles' heel
A fatal weakness, a vulnerable area, as in This division, which is rarely profitable, is the company's Achilles' heel. The term alludes to the Greek legend about the heroic warrior Achilles whose mother tried to make him immortal by holding the infant by his heel and dipping him into the River Styx. Eventually he was killed by an arrow shot into his undipped heel. [c. 1800]
acid test
A decisive trial to determine worth or quality, as in Exposure to brilliant sunlight is the acid test for showing this fabric won't fade. Alluding to a 19th-century chemical test for distinguishing gold from other metals, this term was used figuratively by the early 1900s.
acquaintance
hand. see NODDING ACQUAINTANCE; SCRAPE UP AN ACQUAINTANCE.
acquired taste
Something one learns to like rather than appreciates immediately. For example,
Because it is so salty, caviar for many individuals is an acquired taste, or With its lack of decorative detail, this china pattern is definitely an acquired taste.
[Mid-1800s]
across
hand. In addition to the idiom beginning with ACROSS, also see COME ACROSS; CUT ACROSS; GET ACROSS; PUT ACROSS; RUN ACROSS.
across the board
Applying to all the individuals in a group, as in They promised us an across-the-board tax cut, that is, one applying to all taxpayers, regardless of income. This expression comes from horse racing, where it refers to a bet that covers all possible ways of winning money on a race: win (first), place (second), or show (third). The board here is the notice-board on which the races and betting odds are listed. Its figurative use dates from the mid-1900s.
act
hand. In addition to the idioms beginning with ACT, also see CATCH IN THE ACT;
CLEAN UP (ONE'S ACT); DO A DISAPPEARING ACT; GET IN THE ACT; GET ONE'S ACT TOGETHER; HARD (TOUGH) ACT TO FOLLOW; HIGH-WIRE ACT; IN THE ACT OF; PUT ON AN ACT.

ACTION; PIECE OF THE ACTION; SWING INTO ACTION.
actions speak louder than words
What one does is more important than what one says, as in Politicians need to be reminded that actions speak louder than words. This statement, a proverb found in many languages, including ancient Greek, was first worded in precisely this way in English in Colonial Currency (1736). Also
see ALL TALK; DO AS I SAY, NOT AS I DO.
active duty
Full-time service, as in Julian is 81, but he still comes to the office every day and is very much on active duty. This term comes from the military, where it stands in opposition to reserve, which refers to troops still in the military but not actively engaged. It is occasionally transferred to civilian matters as well. [First half of 1800s]
act of faith
Behavior that shows or tests a person's religious or other convictions, as in Rock climbing with a new, inexperienced partner was a real act of faith. The term is a translation of the Portuguese auto da fé, which referred to the sentencing and execution of heretics (often by burning at the stake) during the Inquisition, when punishing heresy was thought to constitute an assertion of faith. In modern times it is used for more benign circumstances. [Early 1700s]
act of God
An unforeseen and uncontrollable natural event, such as a hurricane, fire, or flood. For example,
The publisher shall publish the work within twelve months except in case of delay caused by acts
of God such as fires or floods or other circumstances beyond its control. It most often appears in legal contracts, where it is used to indemnify one party against a disaster that prevents it from carrying out the contract's terms. [Mid-1800s]
act on
1. Also, act upon. Conduct oneself in accordance with or as a result of information or another action, as in I will act on my lawyer's advice, or The manager refused to act upon the hotel guest's complaints. [c. 1800] 2. Influence or affect, as in The baby's fussing acted on the sitter's nerves.
[c. 1800]
act one's age
Behave more maturely. Although the phrase often is used in asking children to act in a more grown-up fashion (Only babies suck their thumbs; act your age), it also may refer to an adult who is, sometimes deliberately, acting much younger than might be considered appropriate (Grandpa, it's time you stopped climbing ladders and acted your age).
act out
1. Perform or portray something or someone, as in As she read to the class, the teacher had each child act out a different character in the story. [c. 1600] 2. Express unconscious feelings or impulses through one's behavior, without being aware of it. For example, She acted out her anger at her father by screaming at her husband. This meaning comes from 20th-century psychological theory and usually (but not always) refers to negative or hostile impulses and emotions. The term is sometimes used without an object to mean "misbehave" or "behave disruptively," as in The child is acting out in class. [First half of 1900s] In both usages, out means ''openly" or "publicly."
act up
1. Misbehave. For example, With an inexperienced rider, this horse always acts up. [c. 1900] 2. Malfunction, as in I'm not sure what's wrong with my car, but the transmission is acting up. In both usages up means "abnormally."

add fuel to the fire Also, add fuel to the flames. Worsen an already bad situation, as by increasing anger, hostility, or passion, as in Bill was upset, and your making fun of his mishap just added fuel to the fire. This metaphor dates from Roman times?

and it remains in common use. For similar metaphors, see ADD INSULT TO INJURY; FAN
THE FLAMES.

Not only did the club refuse him, but it published a list of the rejected applicants?
that's adding insult to injury, or The nearest parking space was half a mile away, and then, to add insult to injury, it began to pour. The phrase is an ancient one, even older than its often cited use in the Roman writer Phaedrus's fable of the bald man and the fly. A fly bit the head of a bald man, who, trying to crush it, gave himself a heavy blow. The fly then jeered, "You want to avenge an insect's sting with death; what will you do to yourself, who have added insult to injury?" In English it was first recorded in 1748.
addition
hand. see IN ADDITION.

1. Amount to an expected or correct total, as in These figures don't add up, meaning they are not correct. [Mid-1800s] 2.

The term, Latin for "to this," is most often used for committees established for a specific purpose, as in The committee was formed ad hoc to address health insurance problems. The term is also used as an adjective (An ad hoc committee was formed), and has given rise to the noun adhocism for the tendency to use temporary, provisional, or improvised methods to deal with a particular problem. [Early 1600s]
admiration
hand. see MUTUAL ADMIRATION SOCIETY.
ad nauseam
To ridiculous excess, to a sickening degree. For example, I wish he'd drop the subject; we have heard about budget cuts ad nauseam. The term, Latin for "to [the point of] nausea," has been used in English since the early 1600s.
a drag
A tedious experience, a bore, as in After several thousand times, signing your autograph can be a drag. This seemingly modern term was army slang during the Civil War. The allusion probably is to drag as something that impedes progress. [Colloquial; mid-1800s]

see GET THE ADVANTAGE OF; SHOW TO ADVANTAGE; TAKE ADVANTAGE OF; TO ADVANTAGE.

Also see IN A WAY; (SOMEHOW) OR
OTHER.

After everything else has been considered, ultimately, as in Mary has final approval of the guest list; after all, it's her wedding.

after one's own heart
To one's own personal liking, as in He's very patient with the slower pupils; he's a teacher after my own heart. This idiom appears in the King James Bible of 1611 (I Samuel 13:14). [Late 1500s]
after the fact
After an actual occurrence, particularly after a crime. For example, I know the brakes should have been repaired, but that doesn't help much after the fact. The use of fact for a crime dates from the first half of the 1500s. The word became standard in British law and is still used in this way today. The idiom was first recorded in 1769 in the phrase accessories after the fact, referring to persons who assist a lawbreaker after a crime has been committed. Now it is also used more loosely, as in the example above.

In a great hurry, as fast as possible, as in With her term paper due on Monday, she was racing against the clock to finish it, or They were working against time to stay on schedule.

Its figurative use dates from the mid-1900s.
against the grain
Opposed to one's inclination or preference, as in We followed the new supervisor's advice, though it went against the grain.
