(as) right as rain

In good health or order; feeling or working just as someone or something should. I have a broken foot, but once I get my cast off, the doctor says I'll be as right as rain. The project would be right as rain if we could just get the servers to stay online.

Cliché perfectly fine; all right. (Based on the alliteration with r. *Also: as ~.) Lily has sprained her ankle, but after a few weeks of rest she should be as right as rain. All we need to do is tidy the house up; then it will be right as rain.

In good order or good health, satisfactory, as in He was very ill, but he's right as rain now, or If she'd only worked on it another week everything would have been as right as rain. The allusion in this simile is unclear, but it originated in Britain, where rainy weather is a normal fact of life, and indeed W.L. Phelps wrote, "The expression 'right as rain' must have been invented by an Englishman." It was first recorded in 1894.

If someone is as right as rain, they are feeling well or healthy again after an illness or injury. We put a bandage on his knee, gave him a biscuit and a cup of tea and he was right as rain.

In good shape, correct. This simile does not make a great deal of sense, even in rainy Great Britain, where it originated, but it has survived right as a trivet (because a trivet is a tripod and therefore stands firm), as a glove, my leg, and numerous others. Perhaps the “right as” here originally signified “dependable as.” In any event, the term has been around since the late nineteenth century.
