Reference excerpt

The modifier letter turned comma ʻ is a character found in Unicode resembling a comma that has been turned. Unlike a comma, it is a letter, not a piece of punctuation. It is used in a number of Polynesian alphabets as the letter ʻokina to represent the glottal stop, and in the Uzbek alphabet to form the letters Oʻ and Gʻ, which correspond to Ў and Ғ respectively in the Uzbek Cyrillic alphabet.

Encoding

The letter turned comma is encoded at U+02BB ʻ MODIFIER LETTER TURNED COMMA, in the Spacing Modifier Letters Unicode block. In Unicode code charts, the representative glyph used for U+02BB looks identical to that used for the U+2018 ‘ LEFT SINGLE QUOTATION MARK, but this is not true for all fonts. The primary practical difference between the 'letter turned comma' and 'left single quotation mark' is that the 'letter turned comma' is defined in Unicode as a modifier letter [a letter or symbol typically written next to another letter that it modifies in some way] whereas 'left single quotation mark' is defined a type of punctuation mark and an opening quotation mark. For human readers, the difference is imperceptible and unimportant but it has significance in text processing applications.

Use The character is used in many Polynesian languages as ʻokina, a unicameral consonant letter used within the Latin script to mark the phonemic glottal stop. In the Uzbek alphabet, the letter turned comma is used to write the letters Oʻ (Cyrillic Ў) and Gʻ (Cyrillic Ғ). It is sometimes used in Latin transliterations of the Hebrew letter ʻáyin and the Arabic letter ʻayn. The letter turned comma is also often used to romanize aspirated consonants in Armenian.

Worked examples

Example 1 — a first encounter with Modifier letter turned comma

Start with the simplest possible case. Write down what Modifier letter turned comma claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Modifier letter turned comma before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Modifier letter turned comma ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Modifier letter turned comma

In research: Modifier letter turned comma appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Modifier letter turned comma in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Modifier letter turned comma is common in secondary-school and first-year university syllabi. It links to neighbouring topics Latin-script letters, Linguistics stubs, Punctuation, so understanding it makes those chapters shorter.
