* Not yet filled in: This can refer to a space on a form, a questionnaire, or a document that is meant to be completed with information. For example, a "blank check" means you can write any amount on it.
* Not remembered or known: Sometimes we say someone has a "blank" expression when they don't know the answer or are lost in thought.
Specific:
* A blank cartridge: This is a type of ammunition that does not contain a projectile, often used for training or signaling.
* A blank verse: A type of poetry that does not rhyme but follows a regular meter, usually iambic pentameter.
* A blank slate: A metaphor for a person who has no prior knowledge or experience, often used to describe a child or someone starting anew.
It's important to consider the context when interpreting the word "blank." For example, saying "the room was blank" could mean it was empty, or it could describe the room's lack of color or decoration.
