14-letter words containing a, t, y
- primary growth — growth in vascular plants, especially an increase in length, that results from cell division and differentiation of an apical meristem.
- primary letter — a lowercase character having neither a descender nor an ascender, as a, c, e, i, m, n, o, r, s, u, v, w, x, z.

- principal type — The most general type of an expression. For example, the following are all valid types for the lambda abstraction (\ x . x): Int -> Int Bool -> Bool (a->b) -> (a->b) but any valid type will be an instance of the principal type: a -> a. An instance is derived by substituting the same type expression for all occurences of some type variable. The principal type of an expression can be computed from those of its subexpressions by Robinson's unification algorithm.

- protocol layer — (networking) The software and/or hardware environment of two or more communications devices or computers in which a particular network protocol operates. A network connection may be thought of as a set of more or less independent protocols, each in a different layer or level. The lowest layer governs direct host-to-host communication between the hardware at different hosts; the highest consists of user application programs. Each layer uses the layer beneath it and provides a service for the layer above. Each networking component hardware or software on one host uses protocols appropriate to its layer to communicate with the corresponding component (its "peer") on another host. Such layered protocols are sometimes known as peer-to-peer protocols. The advantages of layered protocols is that the methods of passing information from one layer to another are specified clearly as part of the protocol suite, and changes within a protocol layer are prevented from affecting the other layers. This greatly simplifies the task of designing and maintaining communication systems. Examples of layered protocols are TCP/IP's five layer protocol stack and the OSI seven layer model.
