1. Introduction & Historical Context <a name="introduction"></a>

Quotation marks, also called inverted commas, are one of the oldest punctuation marks, originally evolving from the double‑stroke “”** used in medieval manuscripts to signal the beginning of a quoted section. Their primary function is to delimit a quoted text from the surrounding prose, thereby signaling that the words are not the author's own.

Key milestones:

• 12th–13th c.: Manuscript scribes use double strokes to denote speech.
• 16th c.: Early printing presses standardize double quotation marks (“ ”) in English.
• 19th c.: Chicago Manual of Style codifies American vs. British conventions.

Understanding quotation marks requires grappling with syntax, semantics, and pragmatics—the “three pillars” of linguistic theory—since the marks serve as syntactic delimiters and semantic identifiers of source attribution.

2. Formal Definition & Semantics <a name="definition"></a>

Definition.
A quotation mark is a punctuation token q that satisfies:

1. Boundary condition: q appears at the start and end of a substring S such that S is not the host sentence’s original lexical content.
2. Source attribution: S is semantically encapsulated and linked to an external source (speaker, writer, text).
3. Scope: The scope of the quotation is the maximal substring delimited by the matching pair of qs.

Formally, let T be a token sequence.
If q_i and q_j (i < j) are quotation marks, then the quotation Q = T[i+1 : j-1] is a sub‑string with the property that Q is syntactically and semantically distinct from the rest of T.

Semantic function (in the style of Montague semantics):
quote(Q) yields a content expression whose intension is the propositional content of Q. In natural language semantics, this is often represented as:

quote(Q) = λP. P(Q)

where P is a predicate that operates on the content of Q. Thus, quotation marks act as a binder that introduces a new propositional domain.

3. Typographic Conventions <a name="typography"></a>

3.1. American vs. British Styles

• American: Use double quotes for both direct speech and quoting a title or a phrase. Punctuation (comma, period) always goes inside the closing quote.
• British: Use single quotes for direct speech; double quotes are used for quoting a phrase within a quoted sentence. Punctuation (comma, period) goes outside the closing quote.

3.2. Unicode & Font‑Specific Glyphs

• U+201C “ (Left Double Quotation Mark)
• U+201D ” (Right Double Quotation Mark)
• U+2018 ‘ (Left Single Quotation Mark)
• U+2019 ’ (Right Single Quotation Mark)

Tip: In LaTeX, ```text{…}creates left quote and ``text{…}`` creates right quote; in Markdown, use“and”`.
