You are probably referring to the interpunct character (U+00B7) (·) which is a centered dot (e.g: int·er·punct). Although seeing as the interpunct is not commonly known, a hyphen is sometimes used instead (e.g: hy-phen).
A hyphenation is the use of the punctuation mark, the hyphen. The hyphen is used to join separate words and into single words, such as 'merry-go-round' and to separate syllables of a single word into parts, such as 'un-American.'
A hyphen (-) is used to join or combine words or numbers together or to separate syllables. Ex: We have to study African-Americans this year! (joining words) We have ninety-three people in band. (joining numbers) ve-he-ment (separating syllables)

The three symbols of word stress are the primary stress symbol ( ˈ ), the secondary stress symbol ( ˌ ), and the unstressed symbol ( ˈ ). The primary stress symbol is used to mark the syllable that is stressed the most in a word, while the secondary stress symbol marks syllables that are stressed less than the primary stress but more than the unstressed syllables. The unstressed symbol is used for syllables that do not carry any stress.
Syllables are units of pronunciation having one vowel sound, with or without surrounding consonants; or, roughly, the number of distinct sounds in a word, which may have one or more syllables. A prefix is a part of a word, when used, as distinct from the root and the suffix, when used, and inevitably is also a syllable.
A group of symbols that stand for whole syllables of a language is called a syllabary. Syllabaries are different from alphabets in that each symbol represents a full syllable, rather than individual sounds. They are commonly used in languages where each syllable is a separate meaningful unit.
The prefix "cut-" typically means to separate or divide into parts. It is often used in words related to cutting or slicing something.
The name of this symbol (;) is a semicolon. It is used between two clauses to link them rather than making them separate sentences (because they are too closely related to be separate).
