The “Linked” or “Connected” Discourses (Saṁyutta Nikāya, abbreviated SN) is a collection of over a thousand short discourses in the Pali canon. The word “linked” refers to the fact that the texts are collected and organized by topic. In most cases the organizing principle is a particular theme of Dhamma, for example, the five aggregates, dependent origination, the noble eightfold path, mindfulness meditation, or the four noble truths. 

This collection contains the most extensive range of texts on these core themes. In other cases chapters are organized according to the person or kind of person who speaks. This collection has a full parallel in the Saṁyuktāgama (SA) of the Sarvāstivāda school in Chinese translation. In addition, there are two partial collections in Chinese (SA-2 and SA-3) as well as a number of miscellaneous or fragmentary texts in Chinese, Sanskrit, and Tibetan. Much of the organizational structure of SN is shared with SA, suggesting that this structure preceded the split between these two collections.
