A pass can refer to different things depending on the context:
- Mountain pass : A navigable route through a mountain range or over a ridge, which has played a key role in trade, war, and human and animal migration throughout history
. Mountain passes are typically formed between two volcanic peaks or created by erosion from water or wind. They make use of a gap, saddle, col, or notch, and are often found just above the source of a river, constituting a drainage divide
. Passes can be short, with steep slopes to the top, or long, with a valley many kilometers long
. Roads and railways have long been built through passes, and some high and rugged passes may have tunnels bored underneath a nearby mountainside to allow faster traffic flow
- Document : A pass is a document that lets you go somewhere or do something, such as a backstage pass at a concert, a three-day pass from a military base, or a hall pass for using the restroom during class
- Verb : As a verb, "pass" can mean to move past, go by, or to let go without notice, action, remark, etc
. It can also refer to the act of giving something to someone or transferring something from one person to another
. In the context of a test or competition, "pass" can refer to being successful or meeting an acceptable standard
