I was taken aback
Abide by your principles
Abide by your promise
In abject poverty
He was able to combine business with pleasure
All aboard!
About the same time
Forget about it!
I know nothing about it
I will think about it
It is about time
Just be quick about it!
Keep mum about this!
No doubt about it
No one has a certainty about tomorrow
Talk about luck
We will see about that!
What about me?
What were you about to say?
Above all
Above suspicion
Rumors are abroad
Absence makes the heart grow fonder
It is the absolute truth
Absolutely not!
Absolutely!
Absolutely nothing!
How absurdly ridiculous!
Please accept my condolences
It is no accident
Mission accomplished!
Everyone lives according to his means
According to schedule
Under no circumstances
Everyone is accountable for his actions
By all accounts
By a hair's breath
I have an ace in the hole
You hold all the aces
I ache all over
It is an acid test
Act your age
In the act
He acted in bad faith
It is time for action
Actually it was not so
I would not know him from Adam
Do not add fuel to the fire
May I add my two cents worth?
He is a bootlicker
She is the apple of his eyes
I am terribly (or awfully) sorry
That is an awful lot of money
Wipe your tears away
There is no use in crying
Auricularly
Opposites attract
He is addicted to drugs
He is addicted to gambling
No adjective necessary
In the late afternoon
The evil that men do lives after them
Time after time
No need to be afraid
All in good time
All is fair in love and war
It is all part of the game
It is not all that bad
Of all the nerve!
The sun shines equally on all
We are all in the same boat
With all means at hand
With all my heart
No strings attached
He cried like a baby
Back and forth
I had back luck
You scratch my back and I will scratch yours
He backed out
The charge (or scheme or plot) backfired
Neither forward nor backward
She brings home the bacon
Do not let the cat out of the bag
It is in the bag
Birds of a feather
I killed two birds with one stone
Far too good
That is too bad!
You are barking up the wrong tree
The dream has come true
As like as two peas in a pod
I felt like two cents
Just between the two of us
Two is company, three is a crowd
Two heads are better than one
In the twinkling of an eye
It is a real pleasure
You may rest assured
Go jump in the lake!
It runs in the family
