Back on one's feet

Meaning:

When we use this phrase literally, it means that someone has fallen, and that now they are back up standing on their feet. When we use this as an idiom, it means that someone has failed, or had some trouble, or been sick, but that now the situation has improved, and they are OK once again. We often use this one to talk about a person who has recently recovered from an illness. This is almost always used with the "to be" verb.

Example sentences:

1. I'm back on my feet.
2. He can't wait to get back on his feet.
3. Is she back on her feet?

Example dialogue:

A woman has just returned to work from an illness and is talking to her colleague.

A: Hi, Linda. It's nice to be back.
B: Hey, Susan. Welcome back! How are you feeling?
A: I'm doing much better.
B: It's great to see you back on your feet again.
