A list of idioms can be useful, since the meaning of an idiom cannot be deduced by knowing the meaning of its constituent words.
For example, someone might know perfectly well what a bucket is and also understand the meaning of the verb "to kick," completely; however, unless they had already encountered the meaning of the phrase or were able to tell from the context the phrase appears in, they would not know that to kick the bucket is one of the many colorful idioms in the English language meaning to die.
The phrase, "enough money to choke a horse," would not be an idiom because the meaning of the phrase can readily be deduced from knowing the meaning of the individual words that make it up.
Note that idioms are not the same as aphorisms or proverbs, such as, "a bird in the hand is worth two in the bush" or sagacious recommendations like, "don't count your chickens before they hatch".
English has a tremendous stock of idioms. They can be a source of confusion and frustration to non-native users of the langauge. When speaking to people who have recently learned English it might aid their ability to comprehend if one avoids idioms. However, most native English speakers have internalized a large repertoire of idioms which they use often and without thinking much about them so it can be very difficult to censor all idioms from one's speech.
Other meanings for the word idiom include its use as a synonym for dialect. This article concerns itself only with the meaning of the term as defined above however.
The following is a list of idioms in the English language along with their meanings:
Said of someone who boasts in a macho way but cannot be trusted to achieve what he is clearly fond of talking about.
Arm and a leg (to pay)
An extremely high price.
At the end of the day
x will happen. A fatalistic phrase suggesting that whatever criticisms or uncertainties arise, the most probable outcome is likely to be x, where x is what has usually happened in the past. Slightly more obscure than "all things considered" and often a tactical way of terminating a discussion or sustained criticism.
Husband or wife (pejorative, or sometimes satirically affectionate).
Bat out of Hell (like a)
Very quickly (also implies haphazardly, frenetically or in a panic).
To bear fruit
To come to profitable conclusion or to produce some worthwhile thing.
Beat a dead horse
Beating a dead horse is to engage in pointless and repetitive discussion. Beating is more common in American idiom, while Flogging a dead horse is more common in Britain.
Beat around the bush
Procrastinate or hesitate, mainly when one does not want to say something (circumlocution).
Skeptical; requiring proof. (The state's unofficial slogan: "Show me" appears on their license plates).
Between a rock and a hard place
When you are "between a rock and a hard place" you are in a very difficult jam, any forseeable resolution of which will not be pleasant. Another common form of this idiom is "between the Devil and the deep blue sea."
An ostracized or ill-fitting member of a family or group. ("Uncle Ned is the black sheep of the family.")
Boot out
To eject a person from a group or society against their wishes.
Born in a barn
Said to someone who fails to close an external door behind them on entering a building, thus causing a discomforting draught. There are regional variations, in Lincolnshire for instance, one will hear "Do you come from Bardney?" a reference to a windswept fenland village in that English county.
Break a leg
Good luck, especially used to wish luck to stage performers before an opening.
Broken his/her duck
(British), "scored for the first time," or more generally to have avoided complete failure. In British sports slang a "duck's egg" refers to a score of "zero" or "nought". (Similarly "goose eggs" can also mean "00" in American slang.) In the British game of Cricket scoring naught is getting a "duck" and a batter's first run scored is, therefore, "breaking his duck." Generally intended hopefully, as a harbinger of more success to follow. "He's out of his rut and starting to make progress."
Bull in a china shop
A tactless person who upsets others or upsets plans; a very clumsy person.
Burning the candle at both ends
Someone trying to do too much at once, wearing themselves out.
Burning the midnight oil
Studying or working late into, or through, the night.
Bury the hatchet
Make peace with. To end hostilities.
Buy/Bought the farm
To die (possibly a cynical reference to the effect of a life insurance benefits to the beneficiaries; as in "his demise bought the farm").
To purchase something without inspection, thereby creating an opportunity for fraud. Canonical: unethical farmer places a barn-yard cat in a burlap bag (poke) and sells it sight-unseen to another, claiming it contains a piglet. Related to "the cat's out of the bag", below.
This term derives from the practice of badger-baiting, in which a badger is put into a pit and made to fight dogs. To call the badger a bishop is to imply that the badger's overwhelmed condition somehow makes it virtuous, when it is, in fact, just a badger. So, the term means committing the fallacy of projecting virtue on to the oppressed or disadvantaged.
Can of worms
A situation that is hard to deal with, especially one that comes about unexpectedly and intractably. To "open a can of worms" is to get involved with something that is discomforting, hard to resolve, or not easily escaped (closing a container of worms, used as bait by fishermen, generally involves some tricky handling of the wriggling occupants)

Losing sight of the big picture by getting mired down in details
Can't see your nose in front of your face
Being oblivious to something in plain view
Cat amongst the pidgeons

Cat got your tongue?
Asked of someone rendered speechless to emphasize their inability to speak
Cat nap
A short sleep taken during the day. However, this may not necessarily qualify as an "idiom", as the meaning is apparent to some; cats tend to sleep for short intervals (naps) at various times throughout a twenty-four hour period, whereas humans generally sleep for a solid one-third fraction of each day and do not typically "nap" in a catlike manner. Thus, sleeping in this manner is to "nap like a cat", or to take a "cat nap"
A situation from which there is no escape; a problem in which any course of action is likely to result in undesirable consequences. Similar to a "no-win situation" and Hobson's Choice.

Close the barn door after the horse gets out
Refers to not taking action until after a problem has already occurred, usually when it's too late and should have been done sooner. "Closing the stable door after the horse has bolted" is the common British variant
Curiosity killed the cat
As cats are naturally curious, the expression suggests excessive curiosity is not necessarily a good thing, especially where it is not their business.
Cut off your nose to spite your face
To take rash or single-minded action that hurts your own cause in the end. Similar to "throwing the baby out with the bathwater"
A surprise candidate, or competitor; someone who hides their talents or interests. From the metaphor: "He rode in as if on a dark horse in the night" or "No one saw him coming."
Dead and buried
A settled issue. Something no longer needing consideration.
Dead as a doornail
Useless, very distinctly dead. A doornail is the strikeplate for most door knockers. To hold it in place, after it was driven through the door, the pointed end was bent over and buried in the door, to prevent movement. This nail was unrecoverable, so was considered dead to future reclamation, which was apparently common before modern time.

A problem or obstacle that may be trivial in itself, but causes cataclysmic failure because it pushes the total array of problems or obstacles to an intolerable level.

Said of a person that is lacking intellect and/or sanity, even if they may appear at first to possess full mental faculties.
