Parastu is a Persian feminine given name meaning “swallow,” the bird. It is written پرستو in Persian and pronounced approximately pa-ras-TOO. The spellings Parastoo and Parastou represent the same Persian name in different Latin-letter conventions.
The classification as a given name is unusually well documented. Linguist Karine Megerdoomian's MITRE report on the structure of Persian names lists Parastu (“swallow”) among Persian nouns and adjectives used as first names. It is therefore best understood as a Persian nature name, not primarily as a hereditary surname.
Meaning and Formation
The source is the ordinary Persian noun پرستو (parastū), “swallow.” The University of Texas at Austin's Persian transcription guide gives the word as parastū and translates it as “a swallow.” Megerdoomian places Parastu in a productive type of Iranian first name in which a familiar Persian noun or adjective is used directly as a personal name; comparable examples in her discussion include Mahtab (“moonlight”) and Yasaman (“jasmine”).
This is a lexical meaning, not a biography of every bearer. “Swallow” does not by itself show that parents intended a particular symbolism such as spring, freedom, fidelity, return, or good fortune. Those may be personal or literary associations, but the checked linguistic sources do not make any one of them part of the name's established definition.
An Old Word, but Not a Dated First Name
The Persian bird word has a history independent of the personal name. The Dehkhoda Dictionary entry for پرستو defines it as a small bird and records older forms or synonyms such as پرستوک (parastūk) and پرستک (parastak). It also illustrates the noun with passages attributed to the poets Rudaki and Saadi. This establishes that the bird term belongs to the older Persian literary vocabulary.
Those literary examples are not records of people named Parastu. They cannot date the adoption of the word as a feminine name, identify a first bearer, or show continuous personal-name use from a medieval poet's time to the present. The sources reviewed here establish the word's age and the name's modern classification, but not the date when the common noun first became a given name.
Persian Script and Pronunciation
The name and the common noun share the spelling پرستو. Persian script does not use capital letters to distinguish a proper name from an ordinary word, and it normally leaves short vowels unwritten. Context—especially the name's position beside a family name—therefore matters.
The careful transcription parastū marks a long final vowel. A practical English approximation is pa-ras-TOO, with the stress on the last syllable; Behind the Name gives the Iranian Persian pronunciation as /pæ.ɾæs.ˈtuː/. The English r is only an approximation of the Persian sound.
Parastu, Parastoo, and Parastou
The variation is mainly romanization, not three separate etymologies:
- Parastū uses a macron to mark the final long vowel.
- Parastu removes that diacritic and is the spelling used in Megerdoomian's list of Persian first names.
- Parastoo writes the final sound as oo for English readers. *Behind the Name* uses Parastoo as its headword and identifies Parastu as a variant.
- Parastou uses ou for the same final vowel. The British Museum's authority record for the Iranian artist Parastou Forouhar provides a clear institutional example: Parastou is the given name and Forouhar the family name.
A person's own spelling should be preserved. Variant romanizations can be useful when searching catalogues or records, but similar spelling is not enough to merge two identities.
Why “Worship” Is Not the Meaning
Some online explanations connect Parastu with worship or devotion because the Latin spelling resembles Persian words built on پرست. That resemblance is misleading here. The University of Texas transcription guide lists پرستش (parasteš), “worship,” and پرستو (parastū), “a swallow,” as separate vocabulary items. The Persian dictionaries checked for this page likewise define پرستو as the bird. “Worshipper,” “devoted,” or “adoration” should not be presented as an alternative established meaning of this name without a specialist source demonstrating a different derivation.
Given Name or Family Name?
The strongest name-specific source classifies Parastu as a first name, and Behind the Name classifies Parastoo as feminine. A modern database may nevertheless place Parastu in a surname field. That alone does not demonstrate a traditional Parastu family name: field reversal, incomplete indexing, local name order, or later adoption may be involved.
There is also a genuine reason not to make an absolute claim. Megerdoomian notes that modern Iranian last names can be ordinary nouns or adjectives without a visible surname suffix. A particular family could therefore use Parastu hereditarily even though the documented, usual classification is as a given name. Such a case must be established from records showing the name consistently inherited in the family-name position; the bird meaning cannot prove that different bearers share an ancestry.
What the Evidence Does Not Establish
No dependable source reviewed for this article supplied a first historical bearer, a standard diminutive, or a long-term popularity series for Parastu. The sources also do not support a universal religious meaning, personality description, or symbolic promise. These omissions are preferable to turning plausible associations into facts.
