Tanglements are things that are twisted or mixed together and are hard to separate.
Tanglements are usually not good because they make things messy and confusing.
Examples:
The fishing lines were all tanglements and we couldn't use them.
She tried to untangle the tanglements of yarn.
The tanglements of wires behind the TV were a mess.
The tanglements of spaghetti on my plate looked like a big knot.
The tanglements of vines in the jungle were so thick you couldn't walk through them.
The tanglements of thoughts in my head made it hard to think clearly.
