    • hyphen In paleography, a curve placed below the line so as to unite the parts of a compound word, and to indicate that they are not to be separated or read as distinct words: as, —that is, διόσκουροι, not Διο\ς κου%26ροι; —that is, περικλέονς, not πεπι\ κλέους —that is, antevolans, not ante volans, etc. In its use the hyphen is the exact opposite of the diastole or hypodiastole.
    • hyphen In writing and printing, a short line (-) used to connect two words or elements: namely, to connect two words which are so used as properly to form a compound word; to join syllables which are for any purpose arbitrarily separated, as in regular syllabication (as in el-e-men-tal), at the end of a line to connect the syllables of a divided word (as in the third line of this paragraph), to indicate the pronunciation (as in the respellings for the pronunciations in this dictionary), and to indicate or separate the etymological parts of a word, stem, affixes, etc., often without regard to the syllables (as in element-al, intro-duct-ion, su-spic-ious). At the end of such an etymological element it indicates a prefix, as a-, in-, pre-, etc.; before au element it indicates a suffix, as -a, -in, -ous, etc.

In science:

We say that the string σ ∈ [k ]n contains a generalized pattern τ if σ contains a subsequence isomorphic to τ in which the entries corresponding to consecutive entries of τ not separated by a hyphen must be adjacent.

Classical patterns are generalized patterns with all possible hyphens (say, 2-1-3), in other words, those that place no adjacency requirements on σ .
Words restricted by 3-letter generalized multipermutation patterns
Later, Claesson and Claesson and Mansour considered the number of permutations avoiding one or two generalized patterns with one hyphen.

We also define the complement of τ , denoted c(τ ), to be the pattern obtained by substituting ℓ + 1 − τ (i) for τ (i) and leaving hyphens in the same positions (e.g., c(13-2) = 31-2).
