Baseline Grid
A baseline grid is the foundation for consistent typographic rhythm on a
page. It allows the reader to easily follow the flow of the text, which in turn
increases readability.
Cap Height
The height of capital letters above the baseline is referred to as cap height.
This especially applies to „flat“ letters such as L or T (see illustration above).
Diacritic
Pronunciation symbol: A mark near or through an orthographic or phonetic
character, e.g. déjà-vu in the French language or Øre in Norwegian or
Danish language.
Glyph
One particular character or sign of a given writing system. This can either
be a letter like „a“ or a diacritic or ligature consisting of two or more letters.
At any rate, a glyph represents a complete graphic unit.
Grotesque
Grotesque or Gothic is a proper synonym for sans-serif typefaces. They
were deducted from Antiqua type, but sans (french = without) serifs and
the letters show a much more consistent stroke weight than serif typefaces.
