Pronunciation

Forms

se[1] Before a vowel it may be elided to s’.[2] Old Florentine, Sienese and Milanese texts have sed before a vowel.[3]

Etymology

The conjunction “if” is inherited from Late Latin se(d), a Late Latin form recorded from the 6th century, which DELI, GRADIT, Sabatini–Coletti and the GDLI explain as a blend of Latin sī (“if”) with quid (“what”).[4][5][6][7][3] DEI supports the final consonant with the old forms in ⟨sed⟩ before a vowel, as in Brunetto Latini's ⟨sed io ben mi ramento⟩ “if I remember well”, and with the doubling of the consonant that follows the conjunction.[3] Nocentini instead takes it as Latin “sī” under the attraction of che,[8] and Wiktionary leaves both explanations open.[1]

The conjunction is panromance: French si, Occitan si, Catalan si, Spanish si, Portuguese se and Sardinian si.[8] DEI sets the Sardinian, Old Venetian, Provençal, Catalan and Spanish forms in ⟨si⟩, which continue “sī” directly, against Romanian să and the Old French form ⟨se⟩.[3] Meyer-Lübke noted that ⟨se⟩, written in France from the 6th century, may have been formed after the outcome of quia (“that, because”).[9] In Romanian the word is now a particle meaning “that”.[10]

Latin “sī” comes from an older ⟨sei⟩, written in early inscriptions, which goes back to Proto-Italic *sei (“so, thus”).[11][1] It was originally a locative of an old demonstrative Proto-Indo-European *só (“this, that”), used to link clauses with the sense “in this case”, and only later became a subordinating conjunction “in the case that”.[8][11][1] The same old form, with the particle -ce, gave sīc (“so”).[8][1]

Earliest recorded meaning

The first record is in the Ritmo laurenziano, at the end of the 12th century, already with the sense “in the case that”.[4][8][5] It has the line Se mi dà cavai ballano (“if he gives me prancing horses”).[7]

Semantic evolution

In the first half of the 13th century the conjunction also meant “since, given that”, in Iacopo d'Aquino, and before 1294 Brunetto Latini uses it for a clause of doubt.[4] An indirect question with se “whether” follows at the end of the 13th century in the Novellino.[4] Boccaccio has the dubitative use: Non so se a voi quello se ne parrà che a me ne parrebbe (“I do not know whether it will seem to you as it would to me”).[12]

Compounds with adverbs became conjunctions of their own: semmai before 1292, sennò in the 13th century, sebbene and sennonché in the 14th century, and seppure in 1838.[8] As a noun se meant “condition” before 1557 in Girolamo Parabosco, and Tommaseo in 1873 records it for “hesitation, doubt”.[4] The noun survives in the phrase con i se e con i ma, said of doubts and objections that hold up a decision.[6]

Pronunciation

Forms

se[1]

Etymology

The pronoun is inherited from Latin sē (“himself, herself, itself, themselves”), the Latin reflexive pronoun.[4][5][6][15][1] It is the form that the clitic si takes before lo, la, li, le and ne.[5][6]

The same pronoun is Romanian se, Dalmatian se, Sardinian se, Friulian se, French se, Occitan se, Catalan se, Spanish se and Portuguese se.[9] In Romanian, Dalmatian, Italian, Rhaeto-Romance and southern French dialects it also serves as the reflexive of the first and second persons.[9]

Latin “sē”, written ⟨sēd⟩ in Old Latin inscriptions, goes back to Proto-Indo-European *se (“oneself”); the long vowel comes from the stressed form.[16] Cognates include Gothic 𐍃𐌹𐌺 (sik) and Old Church Slavonic сѧ (sę).[16][11]

Earliest recorded meaning

The pronoun is first recorded in the Novellino, at the end of the 13th century, for “to oneself” and as a pleonastic particle.[4][5]

Semantic evolution

Boccaccio uses it before another clitic for the dative of interest: insieme col medico e co' compagni suoi se gli mangiò (“he ate them [the capons] together with the doctor and his companions”).[15] With ne it formed the pronominal verbs of motion, as in Boccaccio's se n'andarono “they went away”.[12]

Alone, in place of si, it is literary and mostly enclitic, as in Petrarch's non pò fermarse (“cannot stop”).[5][6] Tommaseo notes that Venetian uses se for si in every position.[12]

Timeline

  • Late 13th century – The Novellino uses the pronoun se.[4]
  • 1349–1353 – Boccaccio's Decameron has se gli mangiò and se n'andarono.[15][12]

Meanings

Pronoun

  1. Unstressed reflexive pronoun of the third person, singular and plural, used for si before lo, la, li, le and ne: Se l'è dimenticato a casa.[5][6][2]
  2. (literary) Used alone for si, especially attached to the verb.[5][6]

Usage notes

In Tuscan pronunciation the conjunction doubles the consonant that follows it.[17][3] A minor homograph, archaic and literary, is se “so, may it be that”, used in wishes and oaths with the subjunctive: DELI derives it from Latin sīc (“so”), influenced by the conjunction “if”, and first records it before 1294 in Guittone d'Arezzo.[4][15] Dante uses it in Purgatorio 2.16: cotal m'apparve, s'io ancor lo veggia, / un lume (“so, may I see it again, a light appeared to me”).[2][13][15] The stressed reflexive pronoun is written sé.[6]
