The earliest forms of writing have been found in Uruk in Mesopotamia. At first, as in other places, simple pictures were used in Uruk to represent things. The meaning of pictograms is quite obvious.
Subsequently, a link became established between spoken language and pictograms which led eventually to alphabet-based written languages. Parallel to the use of simple pictures as a written version of that which the represent, the pictures became a representation of the sound corresponding to that thing.
If we apply this principle in English, a spoken word such as “terrace” could be written with the pictures for “tear” and “ace”, or “factory” could be written with the pictures for “fact” and “tree” if they were available. In the cuneiform script, syllable sounds were used by scribes in texts together with word signs to enable them to “render human speech effectively in their script” (Michael Roaf, “Cultural Atlas of Mesopotamia” p70). Pictograms came increasingly to represent sounds rather than things.
The step from syllables to smaller sound elements was not far off. Extra filler characters would have become necessary in combination with syllable sounds where a pictogram was not available. Syllable signs broke down into their sound elements.
Word signs have fallen out of usage by and large in alphabet-based languages except in playful contexts: . Snaaaaaaaaaaaaaaaaaaake
