Here's a breakdown:
* Basic signs: Around 600 signs are considered "basic" and represent syllables.
* Logograms: There are also thousands of logograms, which represent entire words.
* Determinatives: These signs are added after logograms to indicate the word's grammatical category.
So, the total number of signs used in cuneiform is quite large, but it varied depending on the language and time period.
It's important to remember that cuneiform evolved over thousands of years and was used to write many different languages, each with its own nuances and variations.
