Romanian phonology

Less frequent vowels

Diphthongs and triphthongs

According to Ioana Chițoran, Romanian has two diphthongs: /e̯a/ and /o̯a/. As a result of their origin (diphthongization of mid vowels under stress), they appear normally in stressed syllables^[4] and make morphological alternations with the mid vowels /e/ and /o/.

In addition to these, the semivowels /w/ and /j/ can be combined (either before, after, or both) with most vowels. One view considers that only /e̯a/ and /o̯a/ can follow an obstruent-liquid cluster such as in broască ('frog') and dreagă ('to mend')^[5] and form real diphthongs, whereas the rest are merely vowel–glide sequences.^[6] The traditional view (taught in schools) considers all of the above as diphthongs.

As can be seen from the examples above, the diphthongs /e̯a/ and /o̯a/ contrast with /ja/ and /wa/ respectively, though there are no minimal pairs to contrast /o̯a/ and /wa/.^[8] Impressionistically, the two pairs sound very similar to native speakers.^[9] Because /o̯a/ does not appear in the final syllable of a prosodic word, there are no monosyllabic words with /o̯a/; exceptions might include voal ('veil') and doar ('only, just'), though Ioana Chițoran argues^[10] that these are best treated as containing glide-vowel sequences rather than diphthongs. In some regional pronunciations, the diphthong /o̯a/ tends to be pronounced as a single vowel /ɒ/.^[11]

Other triphthongs such as /juj/ and /o̯aw/ occur sporadically in interjections and uncommon words.

Vowel alternations

Romanian has vowel alternation or apophony triggered by stress. A stressed syllable has an open vowel, or a diphthong ending in an open vowel, and an unstressed syllable has a mid vowel. Thus /e̯a/ alternates with /e/, /o̯a/ with /o/, and /a/ with /ə/.^[13]

This alternation developed from Romanian vowel breaking (diphthongization) and reduction (weakening). The Eastern Romance mid vowels /e o/ were broken in stressed syllables, giving the Romanian diphthongs /e̯a o̯a/,^[14] and the open vowel /a/ was reduced in unstressed syllables, giving the Romanian central vowel /ə/.

These sound changes created the stress-triggered vowel alternations in the table below.^[15] Here stressed syllables are marked with underlining (a):

This has since been morphologized and now shows up in verb conjugations^[16] and nominal inflection: oaste — oști, 'army' — 'armies'.^[17]

Palatalized consonants

Palatalized consonants appear mainly at the end of words,^[21] and mark two grammatical categories: plural nouns and adjectives, and second person singular verbs.^[22]

The interpretation commonly taken is that an underlying morpheme /i/ palatalizes the consonant and is subsequently deleted. However, /sʲ/, /tʲ/, and /dʲ/ become [ʃʲ], [t͡sʲ], and [zʲ], respectively,^[22] with very few phonetically justified exceptions, included in the table below, which shows that this palatalization can occur for all consonants.

In certain morphological processes /ʲ/ is replaced by the full vowel /i/, for example

• in noun plural genitive formation: școli — școlilor /ʃkolʲ/ — /ˈʃkolilor/ ('schools — of the schools'),
• when appending the definite article to some plural nouns: brazi — brazii /brazʲ/ — /ˈbra.zij/ ('fir trees — the fir trees')
• in verb + pronoun combinations: dați — dați-ne /dat͡sʲ/ — /ˈdat͡sine/ ('give — give us').

This may explain why /ʲ/ is perceived as a separate sound by native speakers and written with the same letter as the vowel /i/.

The non-syllabic /ʲ/ can be sometimes found inside compound words like câțiva /kɨt͡sʲˈva/ ('a few') and oricare /orʲˈkare/ ('whichever'), where the first morpheme happened to end in this /ʲ/. A word that contains this twice is cincizeci /t͡ʃint͡ʃʲˈzet͡ʃʲ/ ('fifty').

In Old Romanian and still in some local pronunciations there is another example of such a non-syllabic, non-semivocalic phoneme, derived from /u/, which manifests itself as labialization of the preceding sound. The usual IPA notation is /ʷ/. It is found at the end of some words after consonants and semivowels, as in un urs, pronounced /un ˈursʷ/ ('a bear'), or îmi spui /ɨmʲ spujʷ/ ('you tell me'). The disappearance of this phoneme might be attributed to the fact that, unlike /ʲ/, it did not play any morphological role. It is a trace of Latin endings containing /u(ː)/, /oː/ (-us, -ūs, -um, -ō), this phoneme is related to vowel /u/ used to connect the definite article "l" to the stem of a noun or adjective, as in domn — domnul /domn/ — /ˈdomnul/ ('lord — the lord', cf. Latin dominus).

Other consonants

This article possibly contains original research. (July 2012)

As with other languages, Romanian interjections often use sounds beyond the normal phoneme inventory or disobey the normal phonotactical rules, by containing unusual phoneme sequences, by allowing words to be made up of only consonants, or by consisting of repetitions. Such exceptional mechanisms are needed to obtain an increased level of expressivity.^[23] Often, these interjections have multiple spellings or occasionally none at all, which accounts for the difficulty of finding the right approximation using existing letters.^[24] The following is a list of examples.

• A bilabial click [ʘ], pronounced by rounding the lips and strongly sucking air between them, is used for urging horses to start walking.^[23]
• Whistling is another interjection surpassing the limits of the phoneme inventory. It is usually spelled fiu-fiu.^[23]
• The dental click [ǀ] (see also click consonants) is used in an interjection similar to the English tut-tut (or tsk-tsk), expressing concern, disappointment, disapproval, etc., and generally accompanied by frowning or a comparable facial expression. Usually two to four such clicks in a row make up the interjection; only one click is rare and more than four can be used for over-emphasis. The Romanian spelling is usually tț,^[25] ttt or țțț.
• The same dental click is used in another interjection, the informal equivalent of "no" (nu in Romanian). Only one click is emitted, usually as an answer to a yes–no question. Although there is rarely any accompanying sound, the usual spelling is nt or nț.
• A series of interjections are pronounced with the mouth shut. Depending on intonation, length, and rhythm, they can have various meanings, such as: perplexity, doubt, displeasure, tastiness, toothache, approval, etc.^[24] Possible spellings include: hm, hâm/hîm, mhm, îhî, mmm, îî, hî. Phonetically similar, but semantically different, is the English interjection ahem.
• Another interjection, meaning "no", is pronounced [ˈʔḿ ʔm̀] (with a high-low phonetic pitch). Possible spellings include: î-î, îm-îm, and m-m. The stress pattern is opposite to the interjection for "yes" mentioned before, pronounced [m̀ˈḿ̥m] (with a low-high phonetic pitch).
• Pfu expresses contempt or dissatisfaction and starts with the voiceless bilabial fricative /ɸ/, sounding like (but being different from) the English whew, which expresses relief after an effort or danger.
• Câh/cîh expresses disgust and ends in the voiceless velar fricative /x/, similar in meaning to English ugh.
• Brrr expresses shivering cold and is made up of a single consonant, the bilabial trill, whose IPA symbol is /ʙ/

Rhythm

Languages such as English, Russian, and Arabic are called stress-timed, meaning that syllables are pronounced at a lower or higher rate so as to achieve a roughly equal time interval between stressed syllables. Another category of languages are syllable-timed, which means that each syllable takes about the same amount of time, regardless of the position of the stresses in the sentence. Romanian is one of the syllable-timed languages, along with most Romance languages (French, Spanish, etc., but not Portuguese), Telugu, Yoruba, Chinese, Indonesian/Malay and many others. (A third timing system is mora timing, exemplified by Classical Latin, Fijian, Finnish, Hawaiian, Japanese, and Old English.)

The distinction between these timing categories may sometimes seem unclear, and definitions vary. In addition, the time intervals between stresses/syllables/morae are in reality only approximately equal, with many exceptions and large deviations having been reported. However, whereas the actual time may be only approximately equal, the differences are perceptually identical.

In the case of Romanian, consonant clusters are often found both in the syllable onset and coda, which require physical time to be pronounced. The syllable timing rule is then overridden by slowing down the rhythm. Thus, it is seen that stress and syllable timing interact. The sample sentences below, each consisting of six syllables, are illustrative:

Mama pune masa – Mom sets the table

Mulți puști blonzi plâng prin curți – Many blond kids cry in the courtyards

The total time length taken by each of these sentences is obviously different, and attempting to pronounce one of them with the same rhythm as the other results in unnatural utterances.

To a lesser extent, but still perceivably, the syllables are extended in time also on one hand by the presence of liquid and nasal consonants, and on the other by that of semivowels in diphthongs and triphthongs, such as shown in the examples below.

A simple way to evaluate the length of a word, and compare it to another, consists in pronouncing it repeatedly at a natural speech rate.

Intonation

A detailed description of the intonation patterns must consider a wide range of elements, such as the focus of the sentence, the theme and the rheme, emotional aspects, etc. In this section only a few general traits of the Romanian intonation are discussed. Most importantly, intonation is essential in questions, especially because, unlike English and other languages, Romanian does not distinguish grammatically declarative and interrogative sentences.

In non-emphatic yes/no questions the pitch rises at the end of the sentence until the last stressed syllable. If unstressed syllables follow, they often have a falling intonation, but this is not a rule.

— Ai stins lumina? [ai stins lu↗mi↘na] (Have you turned off the light?)

— Da. (Yes.)

In Transylvanian speech these yes/no questions have a very different intonation pattern, usually with a pitch peak at the beginning of the question: [ai ↗stins lumi↘na]

In selection questions the tone rises at the first element of the selection, and falls at the second.

— Vrei bere sau vin? [vrei ↗bere sau ↘vin] (Do you want beer or wine?)

— Bere. (Beer.)

Wh-questions start with a high pitch on the first word and then the pitch falls gradually toward the end of the sentence.

— Cine a lăsat ușa deschisă? [↗cine↘ a lăsat ușa deschisă] (Who left the door open?)

— Mama. (Mom did.)

Repeat questions have a rising intonation.

— A sunat Rodica adineauri. (Rodica just called.)

— Cine a sunat? [cine a su↗nat] (Who called?)

— Colega ta, Rodica. (Your classmate, Rodica.)

Tag questions are uttered with a rising intonation.

— Ți-e foame, nu-i așa? [ți-e foame, nu-i a↗șa] (You're hungry, aren't you?)

Unfinished utterances have a rising intonation similar to that of yes/no questions, but the pitch rise is smaller.

— După ce m-am întors... [după ce m-am în↗tors...] (After I came back...)

Various other intonation patterns are used to express: requests, commands, surprise, suggestion, advice, and so on.
