súlmede

Sõlmed is an Estonian noun with several related meanings, depending on context. The form sõlmede is the genitive plural used in phrases such as sõlmede arv (the number of nodes) or in compounds like lümfisõlmed. In everyday language the word can refer to knots in rope, nodes in a network or graph, and lymph nodes in anatomy when part of such terms.

In ropework and textile contexts, a sõlm is a knot tied to fasten or join cords and to secure objects. Knots are valued for reliability, ease of tying and untying, and for their suitability to specific tasks such as securing loads, joining lines, or creating loops. The study and practice of knot-tying cover a wide range of techniques and terminology.

In mathematics, computer science, and related fields, sõlmed denote the nodes of a graph or network. A graph consists of sõlmed connected by edges, and analyses often focus on the number of sõlmed, their arrangement, and how they influence connectivity, flow, or network resilience. The term is common in discussions of networks, circuits, and data structures.

In medicine, lümfisõlmed (lymph nodes) are small, bean-shaped organs that filter lymph fluid and coordinate immune responses. They are distributed throughout the body, with clusters in the neck, armpits, and groin. Enlargement of lümfisõlmed can indicate infection, inflammation, or other health conditions and is a routine focus of clinical examination.

Overall, sõlmed covers knots, nodes in systems, and lymph nodes in biology, illustrating how a single Estonian word bridges physical, abstract, and biological concepts.
