Alright, here is a worksheet on the Greek word roots syn-,sym-,syl-, and sys-. They mean, simply, together and same. These are fertile roots in English, and they give us words like symbiosis, symmetry, synchronize, synergy, and synthesis. All of those words are included in this document. Other common words growing from this root, such as synonym, are not here–but as students learn roots, they will recognize syn means together and same, and will be most of the way to defining the word.
