1969, from hyper- "over, above" + text (n.).

In place of the verbal connectives that are used in normal text, such as topic or transition sentences, hypertext connects nodes ... through links. The primary purpose of a link is to connect one card, node or frame and another card, frame or node that enables the user to jump from one to another. [David H. Jonassen, "Hypertext/hypermedia," 1989]

structural element of fungi, 1866, from Modern Latin plural hyphae (1810), from Greek hyphē (singular) "web," probably a back-formation from hyphainō "to weave, warp, devise, produce," from PIE root *(h)uebh- "to weave" (see weave (v.1)). Related: hyphal.
