|1.||the fourteenth letter of English alphabet, is a vocal consonent, and, in allusion to its mode of formation, is called the dentinasal or linguanasal consonent. Its commoner sound is that heard in ran, done; but when immediately followed in the same word by the sound of g hard or k (as in single, sink, conquer), it usually represents the same sound as the digraph ng in sing, bring, etc. This is a simple but related sound, and is called the gutturo-nasal consonent. See Guide to Pronunciation, 243-246.|

|N - /N/ quant. 1. A large and indeterminate number of objects:
"There were N bugs in that crock!" Also used in its
original sense of a variable name: "This crock has N bugs,
as N goes to infinity." (The true number of bugs is always
at least N + 1; see Lubarsky's Law of Cybernetic Entomology.)|
2. A variable whose value is inherited from the current context. For example, when a meal is being ordered at a restaurant, N may be understood to mean however many people there are at the table. From the remark "We'd like to order N wonton soups and a family dinner for N - 1" you can deduce that one person at the table wants to eat only soup, even though you don't know how many people there are.
3. "Nth": The ordinal counterpart of N, senses 1 and 2. "Now for the Nth and last time..." In the specific context "Nth-year grad student", N is generally assumed to be at least 4, and is usually 5 or more (see tenured graduate student). See also random numbers, two-to-the-N.
