When dealing with grammar (and spelling) it's easy to lose yourself in the similarities between several words. However, if you loosen your interpretations too much, you end up losing the meanings you mean for others you've loosed upon the world.
So, to avoid further confusion, let's look at lose, loose, and loosen.
Lose vs. Loose vs. Loosen
Lose is a verb means that to cease to own or retain something and/or being unable to find something. I lose my socks when I can't find them in the morning, but I also lose my way when my sense of direction gets knocked out of balance.
Loose can be used as an adjective or verb. As a verb, loose means to set free or release something or someone. As an adjective, loose describes something that is not firmly or tightly fixed in place. A person could loose a bird into the wild after helping rehabilitate an injured limb. A person could also tighten a loose nut on a bike to avoid losing a wheel.
Loosen is a verb that means to make less tight. A person could loosen a tie or a handshake, but they don't release it completely.
