Sometimes we interchangeably use the word Lose and Loose in a sentence. I hope the meaning of each word can help to determine which is the correct choice of word.
Use in a sentence:
Lose
I want to lose some pounds before the wedding day.
I need you and I don’t want to lose you.
Loose
The rope has loose ends, it will not be able to hold any longer.
The serial killer is on the loose hence we need to be more careful.
******
I hope this helps. Feel free to share our common mistakes in English language. I will include them on my next post with credit (your name). Ciao!
