+\section{Hieroglyph and glyph}
The term \emph{hieroglyph} or \emph{glyph} is not an exact term.
In epigraphic literature, a \emph{glyph} is considered to be a group of one or more graphemes.
They can represent a syllable, single words or even a whole phrase
(\cite[1]{bricker1986}, (\cite[23]{macrilooper2003})).
+For example, the glyph~\ref{fig:terminology-glyphs-utzapaw} consists of the
+graphemes \grapheme{u}, \grapheme{tz\glottalstop{}a} and \grapheme{wa} representing the phrase
+\mayan{u tz\glottalstop{}apaw}, ``she/he erects it''.
+The glyph~\ref{fig:terminology-glyphs-ixwinikhaabajaw} consisting of the
+graphemes \grapheme{ix}, \grapheme{winikhaab} and \grapheme{ajaw}
+and represents the noble title \mayan{ix winikhaab ajaw}, ``Ruler Lady Winikhaab''.

+\section{Glyph block and collocation}
\emph{Glyphs} are usually arranged in regular rectangular shapes called a \emph{glyph block}.
\textcquote[23]{macrilooper2003}{The rectangular shape of \emph{glyph blocks} results from
the arrangement of texts into rows and columns}.
