* Represent objects or activities directly.
* Often used for simple, concrete objects like a house, person, or plow.
* For example, a picture of a house might represent the concept of "home".
Ideograms
*Represent abstract ideas or concepts indirectly through associated objects or actions.
* Often used for more complex, abstract concepts like love, justice, or courage.
* For example, a picture of a heart might represent the concept of "love".
Logograms
* Represent entire words or morphemes, not just individual sounds or objects.
* Often used for complex words that would be difficult to represent with a single pictogram or ideogram.
* For example, the cuneiform sign for the word "king" might be a combination of the pictographs for "man" and "power".
Syllabograms
* Represent syllables, not just individual sounds.
* Often used to write foreign words or names that could not be represented with existing pictographs, ideograms, or logograms.
* For example, the cuneiform sign for the name "Babylon" might be a combination of the syllables "ba", "bi", and "lu".
Numbers
* Sumerian cuneiform also included a system of numerals that used wedge-shaped marks to represent different numbers.
* The basic unit was the "1", which was represented by a single vertical wedge.
* Multiples of 1 were represented by additional vertical wedges, while multiples of 10 were represented by horizontal wedges.
* For example, the number 12 would be represented by two horizontal wedges and two vertical wedges (𒐌).
