Baseline

An imaginary line on which most letters "sit". As such, it equals the height of an em square. The expected result of a baseline is to reference the height with which text is aligned. The alignment ranges from ascenders, which are the upper strokes in b, d, and h, down to descenders like j or y.

Asymmetry

The degree of difference between the two sides of an object or system.

Aperture

The setting on a camera's lens which controls how much light comes into the camera. Aperture settings can usually be set to F-stop values ranging from F1.4-F22. The higher the aperture value, the smaller the opening is, and vice versa, which affects the depth of field in photos and how much light reaches and illuminates a subject or scene in a photo.

Italics

A type of typographical contrast used to convey emphasis. Italics were initially developed for the printing press and are now widely used in print, web design, public signs and labelling systems.

Design Debt

A concept used in systems design to describe the negative consequences of making seemingly innocuous design changes. Shorthand for a product's delayed but inevitable need to be reworked due to earlier, seemingly trivial decisions not having been fully thought through in the original release.

Designers incur this "debt" by making quick and easy choices that save time in the present but cause more complex problems later on down the road when it becomes necessary to change or add something.

Abstract Mark

An abstract mark is a type of logo where instead of being a recognizable object from everyday life, it is an abstract geometric form representing a business or brand. Famous examples include the BP starburst logo, and the Pepsi divided circle.

Brand

A name, symbol or other distinctive feature that distinguishes one business's product from another's, often associated with a logo, design, slogan and other items.
