To no avail
With no effect, unsuccessful.My complaints to the company were to no avail and nothing was done.
To hell and gone
Very much gone, gone to hell.The situation was already to hell and gone when the manager arrived at the office.
To heel
To be under control.The army brought the citizens to heel when they entered the town.
To date
Until the present time.To date there is no indication that the workers will negotiate a new contract.
To boot
In addition, also.Our hot water tank is not working and to boot our kitchen stove is also having problems.
To beat the band
Very much, very fast.We were working hard to beat the band in order to finish our work early and go home.
To be sure
Without a doubt, certainly."To be sure it would be better to talk to the store manager rather than the clerk."
To be safe
To be cautious, to be careful.I took some extra money out of the bank just to be safe and have enough money for the weekend.
To be on the safe side
To be safe, to be cautious, to be very well prepared.I decided to take my umbrella to school to be on the safe side.
To and fro
From one place to another and then back again, back and forth.We went to and fro between the two items as we tried to decide what to buy.
