one' - outs
- One's bark is worse than one's bite
- one's better half
- one's blood be up
- one's blood run cold
- one's days are numbered
- one's eyes are bigger than one's stomach
- One's heart goes out to someone
- One's heart is in one's mouth
- one's heart is in the right place
- one's heart is set on
- one's heart misses a beat
- one's heart skips a beat
- one's heart stands still
- one's luck be in
- one's luck runs out
- one's name is mud
- one's note is in the air
- one's number is up
- one's tail is between one's legs
- one's way of life
