Fe, Qâf, Kâf, Gâf: ف ق ک گ

The letters ف، ق، ک، گ form two useful visual neighborhoods. ف and ق both have dots and rounded bowls, while Persian ک and گ share a base shape distinguished by گ’s extra stroke. All four connect on both sides. In modern Iranian Persian their usual readings are f, merged q/gh, k, and g.

Two of these letters also identify properly encoded Persian text. Persian ک is not the Arabic character ك, and گ is one of the four letters added to the Arabic-based script for Persian. Correct code points matter for search, sorting, fonts, text-to-speech, and answer checking even when a wrong glyph happens to look plausible.

The four joining forms

Each letter has isolated, initial, medial, and final forms. The horizontal extension in this chart marks an attachment point; you do not type it as part of normal words.

For ف/ق, count the dots and inspect the whole bowl: ف has one dot, while ق has two. For ک/گ, look for the added stroke over گ. The real-word pair کم kam “little” and گم gom “lost” is a compact visual minimal pair: that one extra stroke changes both consonant and meaning.

Fe: a stable f

ف has the uncomplicated value f in inherited words and loans, in every position and register. In فردا it begins the word; in دفتر it is medial; in کیف it is final. A non-connecting neighbor can interrupt the visible line without changing ف itself.

Short a, e, and o remain unwritten in all three ordinary targets. دفتر records the consonants d-f-t-r; knowing the word supplies daftar. Adding letters to represent each short vowel would create a different, misspelled skeleton.

Qâf: stable spelling, variable merged sound

In most contemporary Iranian Persian, ق and غ no longer contrast as separate phonemes. Their shared pronunciation varies with speaker and phonetic position, and may sound more stop-like or more fricative-like. This is normal in both (careful-spoken) and (colloquial: Tehran) speech; the distribution of variants is pronunciation, not a license to respell words.

This guide romanizes written ق as q and غ as gh. The distinction lets learners recover the correct letters even though the normal Iranian sounds overlap.

ق is frequent in Arabic-derived vocabulary, including قیمت and فرق, but its occurrence is not limited to elevated prose. These are everyday words. The spelling is identical in informal messages, formal reports, and literature. Only deliberately phonetic colloquial writing may vary in other parts of a word; swapping ق and غ is not a general colloquial convention.

Persian kâf and gâf

ک represents k and must be encoded as Persian kaf U+06A9. Arabic ك U+0643 is a different character. Persian keyboards produce ک; copied Arabic text is a common source of the wrong code point. See Persian Kaf and Yeh for a focused Unicode comparison.

گ represents g. It belongs to the Persian extension of the script, alongside پ، چ، and ژ. That fact does not make Persian “Arabic plus four letters”: Persian uses its own sound system, spelling conventions, vocabulary layers, and productive morphology.

The last sentence shows how much useful structure ordinary Persian spelling retains. Spaces separate words; the ZWNJ in می‌کنم keeps the aspectual prefix attached without joining it visibly to the verb; ی and ا record long vowels; and the remaining short vowels come from lexical knowledge. The script is selective, not random.

Common Mistakes

1. Using Arabic ك in a Persian word. Visual similarity does not make the code points interchangeable.

2. Missing the extra stroke of gaf. This can produce another real word, so spell-checking may not catch it.

3. Replacing qâf with gheyn because the sounds have merged. Pronunciation does not determine the conventional letter.

4. Omitting the ZWNJ before plural ها. The suffix is attached with a half-space in standard orthography.

5. Building a word left-to-right with visible spaces. Persian words use right-to-left character order and normal joining.

Key Takeaways

All four letters connect on both sides. Count dots for ف/ق, look for the added stroke in گ, and always type Persian ک. Read ق with the ordinary Iranian qâf/gheyn sound while preserving its spelling. As with omitted short vowels, the distinction between ق and غ lives partly in the stored identity of each word: Persian orthography records more than pronunciation alone.
