Comparatives and Superlatives in Persian

In Brief

Add ‌تر (-tar) to most adjectives to mean “more” or English “-er”: سردتر (sardtar, “colder”). Add ‌ترین (-tarin) for “most” or “-est”: سردترین (sardtarin, “coldest”). In a comparison, از (az) introduces the standard being compared: امروز سردتر از دیروز است means “Today is colder than yesterday.”

Overview

A comparative is a form that compares two people, things, places, times, or situations: larger, less expensive, or more interesting. A superlative identifies the highest or lowest degree within a group: the largest, the least expensive, or the most interesting. Persian forms both very regularly, so you do not need to choose between English-style -er and more.

This B1 topic builds on ordinary Persian adjectives. Persian adjectives normally follow a noun through ezafe (the short linking sound -e or -ye): کتابِ جالب (ketāb-e jāleb, “an interesting book”). Comparative adjectives can occupy the same position: کتابِ جالب‌تر (ketāb-e jāleb-tar, “a more interesting book”). Superlatives, however, most often come before the noun: جالب‌ترین کتاب (jāleb-tarin ketāb, “the most interesting book”).

English speakers can rely on one convenient principle: adjective length does not change the Persian pattern. Both بلندتر (bolandtar, “taller”) and جالب‌تر (jāleb-tar, “more interesting”) use the same ending. Persian adjectives also do not change for gender or plural number.

How It Works

The two endings

In careful Persian spelling, تر and ترین are usually joined to the adjective with a zero-width non-joiner: the small invisible separator seen in بزرگ‌تر and بزرگ‌ترین. It keeps the word visually connected while preventing letters from joining incorrectly. You may encounter spelling without this separator online, but بزرگ‌تر is the standard form.

Degree	Formation	Persian	Meaning
Plain adjective	adjective	بزرگ (bozorg)	big, large
Comparative	adjective + ‌تر	بزرگ‌تر (bozorgtar)	bigger, larger
Superlative	adjective + ‌ترین	بزرگ‌ترین (bozorgtarin)	biggest, largest

The endings work with short and long adjectives alike:

Plain adjective	Comparative	Superlative
سرد (sard, cold)	سردتر (sardtar, colder)	سردترین (sardtarin, coldest)
سریع (sari', fast)	سریع‌تر (sari'tar, faster)	سریع‌ترین (sari'tarin, fastest)
زیبا (zibā, beautiful)	زیباتر (zibātar, more beautiful)	زیباترین (zibātarin, most beautiful)
گران (gerān, expensive)	گران‌تر (gerāntar, more expensive)	گران‌ترین (gerāntarin, most expensive)
باهوش (bāhush, intelligent)	باهوش‌تر (bāhush-tar, smarter)	باهوش‌ترین (bāhush-tarin, smartest)

The pronunciation of the ending remains -tar or -tarin. Transliteration may show a hyphen for clarity even though it represents a suffix, not a separate spoken word.

Comparing two things with از

Use this basic pattern:

A + comparative adjective + از + B + است

Here, A is the subject (the person or thing being described), and B is the standard of comparison—plainly, what A is measured against.

تهران بزرگ‌تر از اصفهان است.
Tehrān bozorgtar az Esfahān ast.
“Tehran is bigger than Isfahan.”

Persian از commonly means “from,” but after a comparative it corresponds to English “than.” Do not translate each occurrence in isolation; the comparative form makes its role clear.

In everyday speech, است (ast, “is”) is often pronounced ـه (-e) and attached in writing in informal contexts:

این ارزون‌تر از اونه.
In arzun-tar az une.
“This is cheaper than that one.”

The formal written versions are ارزان‌تر rather than colloquial ارزون‌تر, and آن است rather than اونه.

Comparative adjectives with nouns

A comparative can directly describe a noun. Like an ordinary adjective, it usually follows that noun and is linked by ezafe:

• خانهٔ بزرگ‌تر (khāne-ye bozorgtar) — the bigger house / a bigger house
• راهِ کوتاه‌تر (rāh-e kutāhtar) — the shorter route
• روشِ مؤثرتر (ravesh-e mo'ssertar) — a more effective method

Persian has no article exactly equivalent to English a or the. Context determines whether خانهٔ بزرگ‌تر means “a bigger house” or “the bigger house.”

Superlatives before a noun

The most useful superlative pattern is:

superlative adjective + noun

• بزرگ‌ترین شهر (bozorgtarin shahr) — the biggest city
• بهترین انتخاب (behtarin entekhāb) — the best choice
• سخت‌ترین سؤال (sakht-tarin so'āl) — the hardest question

This order deserves attention because it differs from the normal adjective pattern. Compare:

Meaning	Persian structure	Example
a large city	noun + ezafe + adjective	شهرِ بزرگ (shahr-e bozorg)
a larger city	noun + ezafe + comparative	شهرِ بزرگ‌تر (shahr-e bozorgtar)
the largest city	superlative + noun	بزرگ‌ترین شهر (bozorgtarin shahr)

An English the is normally built into the interpretation of this superlative construction; Persian does not add a separate definite article.

Naming the group

To say “the best student in the class” or “the largest city in Iran,” place the group or domain after the noun, commonly with an ezafe phrase or a preposition:

• بهترین دانش‌آموزِ کلاس (behtarin dānesh-āmuz-e kelās) — the best student in the class
• بزرگ‌ترین شهرِ ایران (bozorgtarin shahr-e Irān) — the largest city in Iran
• یکی از معروف‌ترین شاعرانِ ایران (yeki az ma'ruf-tarin shā'erān-e Irān) — one of Iran’s most famous poets

English often uses in after a superlative, but Persian chooses the natural relation for the noun phrase; do not automatically insert در (dar, “in”) in every case.

Important high-frequency forms

Several common comparison words should be learned as complete vocabulary items:

Base idea	Comparative	Superlative	Meaning
خوب (khub, good)	بهتر (behtar)	بهترین (behtarin)	better; best
بد (bad, bad)	بدتر (badtar)	بدترین (badtarin)	worse; worst
زیاد (ziyād, much/many)	بیشتر (bishtar)	بیشترین (bishtarin)	more; most, greatest amount
کم (kam, little/few)	کمتر (kamtar)	کمترین (kamtarin)	less/fewer; least/fewest

بهتر and بهترین do not transparently use خوب, so they feel irregular to a learner. بدتر, بیشتر, and کمتر contain the familiar comparative ending, but their meanings and frequency make them worth memorising as units. In standard usage, خوب‌تر is not the normal neutral replacement for بهتر.

Common Mistakes

Using English “more” as a separate word

• Wrong: بیشتر زیبا for “more beautiful”
• Right: زیباتر (zibātar)
• Why: Persian normally attaches ‌تر directly to the adjective. Unlike English, it does not switch to a separate more merely because the adjective is long.

Leaving out از before the comparison target

• Wrong: امروز سردتر دیروز است.
• Right: امروز سردتر از دیروز است.
• Why: When both sides of the comparison are stated, از introduces the thing or time being used as the standard.

Putting an attributive superlative after the noun

• Awkward for the intended basic meaning: دانشجوی باهوش‌ترین
• Right: باهوش‌ترین دانشجو
• Why: An ordinary or comparative adjective follows a noun, but the standard attributive superlative precedes it.

Adding ezafe between a superlative and its noun

• Wrong: بهترینِ کتاب when you mean “the best book”
• Right: بهترین کتاب
• Why: In the regular superlative + noun pattern, no ezafe links the superlative to the following noun. بهترینِ کتاب‌ها is a different structure meaning “the best of the books.”

Forming the comparison of خوب regularly

• Nonstandard as the neutral choice: خوب‌تر / خوب‌ترین
• Right: بهتر / بهترین
• Why: The everyday comparative and superlative of خوب are بهتر and بهترین. Learn them as a set.

Copying English “in” mechanically

• Unnatural: بهترین دانشجو در کلاس when naming the class as part of the noun phrase
• Natural: بهترین دانشجوی کلاس
• Why: Persian often expresses “the best student in the class” as “the class’s best student,” using ezafe rather than در.

Usage Notes

In conversation, the verb است is frequently reduced, and adjective pronunciation can also reflect colloquial vocabulary: این یکی بهتره (in yeki behtare, “this one is better”) and اون ارزون‌تره (un arzun-tare, “that one is cheaper”). Learn to recognise these forms, but use standard spellings such as آن and ارزان‌تر است in formal writing.

A comparison does not always state both items. این بهتر است means “This is better” when everyone knows the alternatives. Likewise, یک میزِ کوچک‌تر می‌خواهم means “I want a smaller table”; the current table or an earlier option supplies the comparison silently.

بیشتر and کمتر do more than modify adjectives. They can express amount, number, or frequency: وقتِ بیشتری (“more time”), افرادِ کمتری (“fewer people”), and بیشتر ورزش می‌کنم (“I exercise more”). English distinguishes less from fewer, but Persian commonly uses کمتر for both meanings; the noun and context clarify whether amount or count is involved.

Comparatives are not always purely factual. بهتر است... often introduces advice and means “it is better to…”: بهتر است زودتر برویم (“We had better leave earlier” / “It is better that we leave earlier”). Here بهتر evaluates an action rather than directly comparing two named objects.

Beyond the Basics / Advanced Use

A superlative meaning without ‌ترین

The pattern از همه + comparative literally compares someone or something with everyone or everything, but naturally has a superlative meaning:

مریم از همه آرام‌تر صحبت می‌کند.
Maryam az hame ārām-tar sohbat mikonad.
“Maryam speaks more quietly than everyone else,” or naturally, “Maryam speaks the most quietly.”

This structure is especially useful when the compared quality functions like an adverb—that is, when it describes how an action happens. Persian can use many adjectives adverbially without changing their form, as in آرام صحبت کردن (“to speak quietly”).

“One of the most …”

Use یکی از (“one of”) followed by a superlative and a plural noun:

شیراز یکی از زیباترین شهرهای ایران است.
Shirāz yeki az zibātarin shahrhā-ye Irān ast.
“Shiraz is one of the most beautiful cities in Iran.”

Notice that the noun is plural (شهرها, cities), just as the meaning requires a set containing several members.

A superlative used without an expressed noun

A superlative can stand alone when the omitted noun is obvious. It then commonly takes ezafe before the group:

• بهترینِ آن‌ها (behtarin-e ānhā) — the best of them
• کوچک‌ترینِ این سه تا (kuchektarin-e in se tā) — the smallest of these three

This explains why ezafe appeared to be “missing” in بهترین کتاب but appears in بهترینِ آن‌ها. In the first, بهترین directly modifies a following noun. In the second, it is used as a noun-like expression and links to an “of” phrase.

Repeated comparatives

Persian can repeat a comparative to show gradual change:

• هوا سردتر و سردتر شد. — “The weather became colder and colder.”
• تعدادشان بیشتر و بیشتر می‌شود. — “Their number is increasing more and more.”

Another productive pattern is هرچه …تر، …تر (“the more …, the more …”):

هرچه تمرین بیشتر باشد، نتیجه بهتر است.
“The more practice there is, the better the result.”

These patterns extend the same basic ‌تر ending into relationships between changing qualities.

Intensifying a comparison

Words such as خیلی (kheyli, “much/a lot”), کمی (kami, “a little”), and حتی (hattā, “even”) can modify a comparative:

• این مدل خیلی گران‌تر است. — “This model is much more expensive.”
• اتاق دوم کمی روشن‌تر است. — “The second room is a little brighter.”
• امروز حتی گرم‌تر از دیروز است. — “Today is even warmer than yesterday.”

English speakers should note that very bigger is impossible in standard English, while Persian خیلی بزرگ‌تر is natural and means “much bigger.” Here خیلی strengthens the difference, not the plain adjective.

Practice Tips

1. Build three-form sets. Choose ten useful adjectives and say the plain, comparative, and superlative forms aloud: سرد، سردتر، سردترین. Include خوب، بهتر، بهترین as a special set.
2. Compare real choices. Use menus, travel routes, phones, or apartments and make sentences with the full frame A + ‌تر از + B + است. Then omit B when context makes it obvious.
3. Contrast the two noun patterns. Pair a comparative phrase with a superlative one: کتابِ جالب‌تر (“the more interesting book”) versus جالب‌ترین کتاب (“the most interesting book”). This trains the word-order change, which is often harder than the suffixes themselves.
