THANK YOU! In the last 6 months everyone seems to be writing 'loosing'. THE WORD YOU ARE LOOKING FOR IS LOSING.
L-O-S-I-N-G. You are losing the match, you are losing your talent, you are losing your virginity! The second definition is wrong, you would say 'loosening'
Newspaper Executive: Cristiano, this is the last straw, 'loosing' is not a word! I'm firing you!
Cristiano Ronaldo: Oh, I didn't know I had to be able to spell to do this job, I guess i'm just an idiot! Haha
Gerund form of "loose" (of an arrow). The act of firing an arrow in archery.
So rare as to be unusable. If in any doubt at all, use the word with the spelling and meaning for "losing".
