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)
Commas are used to show the division. They can be used to differentiate two word syllables.
One prefix would be un-, as in unimaginable.
A hyphen is a punctuation mark that is used to link words or separate syllables. The three main cases for their usage are to show word breaks, in compound words and to join prefixes to other words.
This symbol is used for syllables: σ
The word prefix has two syllables. When used as a verb, the stress is no the second syllable. The syllables are pre-fix'.
The symbol u means micro, which is the prefix for one millionth.
A hyphen is used to separate a prefix from a proper noun or adjective, especially when the combination could be confusing or misleading without it.
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.
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).
A slash. Example: \ or the famous /
A punctuation mark that is used to connect to words together and separate syllables.(e.g. blahblahblah-blahblahblah-blahblahblah.)
The hyphen is a dash used to separate the syllables in hyphenated words such as built-in. On a keyboard, the minus sign is used to make a hyphen.
The symbol 'u' is often used in place of the prefix 'micro-' in math and physics.AnswerThe symbol U is used to represent voltage. In this context, a lower-case 'u' represents an instantaneous AC voltage. In thermodynamics, it is used to represent internal energy.
