slash (/):

slash (/) [1]: a symbol which is used, especially in phonological analysis, to separate the description of the change (to the left) from the description of the environment (to the right). It can be read "in the environment of". For example, AB / C__D means that A is changed to B in the following environment: when it is preceded by C and followed by D. AB is the description of the change, and C__D is the description of the environment. See also single arrow (), long underline (__). [Spanish: diagonal [1]]

slash (/) [2]: a symbol that is used, especially in informal linguistic description, to separate alternative elements. For example, the root "tôka" of Nahuatl can be glossed 'bury/plant'; that is, sometimes it is translated 'bury' and sometimes 'plant'. This use of the slash can also indicate an alternation. For example, "in-/im-/ir-/il-" are different forms of the same negative prefix in English, as in "inadmissible", "impossible", "irrelevant" and "illegal". Compare tilde [2] (~), braces {...}. [Spanish: diagonal [2]]

slash (/) [3]: a symbol which is used in combination with letters to create new phonetic symbols, for example, the slashed-O (Ø). In this usage, the slash does not have any consistent meaning from one letter to another. [Spanish: diagonal [3]]

slashes /.../ [4]: symbols that are used in pairs to enclose phonemic material. For example, /k/ means 'the phoneme k'. Contrast (square) brackets [1] [...]. [Spanish: diagonales [4]]
