‘Syntactic doubling’ of Italian consonants

Single Italian consonants become pronounced as double (long) consonants (‘geminates’) if they follow:

• a stressed vowel
• some short unstressed words

The Italian name for this process is raddoppiamento syntattico (‘syntactic (re)doubling’), or sometimes rafforzamento fonosyntactico (‘phonosyntactic stregntening’).

‘Syntactic’ refers to the fact that the doubling crosses word boundaries, unlike in word-internal geminate consonants as in [gattto] ‘cat’ or [anno] ‘year’.  

After a stressed vowel

The 1^st place where syntactic doubling occurs is immediately after a word ending a stressed vowel. Examples:

• caffè forte ‘strong coffee [kafˌfɛ‿ f.ˈfɔɾte]
• città bella ‘beautiful city’ [ʧitˌta‿ b.ˈbɛlla]
• città di mare ‘seaside city’[tʃitˈta‿ddi‿ˈmaːre]
• dà molto ‘gives a lot’ [ˈda m.ˈmolto]
• dimmi ‘tell me’
• fammi un favore ‘do me a favour’

In the phonetic transcriptions in this post, [ˌ] shows that the following syllable is unstressed and [ˈ] shows that it is stressed.

The spelling typically captures the doubling of the consonant if the 2 words are written as one (eg dimmi) , but not if they are written separately (eg dà molto ) .

After some unstressed words

The other place where syntactic doubling occurs is after some short unstressed words whose Latin ancestors ended in a consonant. Examples include:

• a (‘to, at’, Latin ad) a < ad ‘to’: a casa (‘to [the] house / home’, Latin ad casam ‘to + house’).
  Italian a (‘at, to’) retains variant ad before some words starting with a vowel.
• da (‘from, to’, from Latin de+ab (‘of’+ ‘from’): da me ‘from me’ [da m.ˈme], da fare ‘to do’ [da f.ˈfare]
• e (‘and’, Latin et): eppure ‘and yet’ [ep.ˈpure] from e ‘and’ + pure. Often written in one word as eppure but can be written in 2 words as e pure.
  Galileo is often supposed (possibly incorrectly) to have said eppur si mouve (‘and yet it [the Earth] moves’) after the Spanish Inquisition forced him to recant his conclusion that the Earth moves around the Sun (rather than vice versa). And yet it moves – Wikipedia
  Italian e (‘and’) retain variant ed before some words starting with a vowel.
• che (‘what, that’ Latin ‘quid’: 
  dice che vuole ‘she says that she wants to’ [ˈdiʧe ke v.ˈvwɔle]; 
  i bambini che vedi ‘the children that you see’ [i bamˈbini ke v.ˈvedi];
  che dite? ‘what are you saying?’ [ˌke d.ˈdite]
• è (‘is, Latin est): è vero ‘it is true’ [ˌɛ v.ˈvero]
• né (‘neither / nor’ Latin nec): né caldo né freddo ‘neither hot nor cold’ [ne k.ˈkaldo ne f.ˈfreddo]
• o (‘either/or’ Latin aut: ossia (from o sia) ‘that is to say (lit. or be.it)’ [os.ˈsia]
• più (‘more’, Latin plus): più morto che vivo ‘more dead than alive’ [ˌpju m.ˈmɔrto ke v.ˈvivo]; sì (‘thus’, Latin sic); 
• se (‘if’, from Latin si quid (‘if what’) via post-Imperial Latin sed): se puoi ‘if you can’ [se p.ˈpwɔj]

• sta (‘stands, is’, Latin stat): sta bene ‘it is good’ [ˌsta b.ˈbɛne]
• sto (‘I stand’, Latin stam): sto male ‘I am unwell’ [ˌstɔ m.ˈmale]
• tre (‘three’, Latin tres): tre cani ‘three dogs’ [ˌtre k.ˈkani]

In many of these cases, the Latin word-final consonant assimilated to the initial consonant of the following word. Later, the stand-alone words lost their terminal consonants as Latin evolved into Italian (for example, ad > a, et > e). But within phrases the assimilated consonant persisted, leaving no present-day clue of its origin.

For instance, [kk] resulting from assimilation in informal Latin of /-d#k-/ ad casam ‘to [the] house / home’ persists today as a casa with [kk]. On the other hand, no syntactic doubling occurs in la casa ‘the house’ because Latin illa (‘that’, the source of Italian la ‘the’) had no final consonant to feed assimilation.

Assimilation is a process that makes one sound resemble a nearby sound. For more on assimilation, please see https://languagemiscellany.com/tag/assimilation/

Syntactic doubling in compounds and by analogy

Syntactic doubling also occurs:

• in a few compound words in which the last element is one of the short words mentioned above. Examples include:
  – come (‘as, like’, from Latin quomodo+et ‘like, as’: come noi ‘like us’ [ˌkome n.ˈnoj]
  – qualche (‘some’, from latin quale+quid ‘which’ + ‘what’: qualche giorno ‘some day’ [ˌkwalke d.ˈʤorno]
  –  così (from (ec)cum sic ‘so’: così male ‘so bad’ [koˌsim.ˈmale], cosiddetto ‘so-called’
• in a few words with penultimate stress, apparently through analogies which are not wholly clear. Examples are: ma (‘but’, Latin magis, tra and fra  (Latin intra and infra ‘between, within’), sopra (‘above’ Latin supra), contra (‘against’, Latin contra) and dove ( ‘where’ Latin de + ubi (‘from’ + ‘where’).
• (by analogy) in some monosyllabic verbs

Monosyllabic verb forms

In the 3^rd person singular of the present tense, the monosyllabic forms da (‘gives’, from Latin monosyllabic dat) and sta (‘stands’, Latin stat) trigger syntactic doubling.

By analogy, some other monosyllabic present tense 3^rd person singular forms also trigger syntactic doubling. Those forms are fa ‘does’ (Latin facit), ha ‘has’ (Latin habet), sa ‘knows’ (Latin sapit), and va ‘goes’ (Latin vadit). It is as if those forms derived from hypothetical monosyllabic forms *fat, *(h)at, for habet), *sat, and *vat.

Future tense

The future tense is formed by suffixing forms of avere (‘have’) to a stem based on the infinitive. Thus, the 3^rd person singular of the future tense (avrá) ends in a stressed version of ha (‘has’—the letter <h> is silent in Italian). So, that form also triggers syntactic doubling. An example is andrò piano ‘I will go slowly’ [anˌdɾɔ p.ˈpjano].

Thus, the 3^rd person singular of the future tense is one trigger of syntactic doubling. Wheeler and O’Neill suggest that this fact may have played a role in expanding the set of triggers to include all polysyllables with stressed final vowels.

Other varieties of Italian

The discussion in this post focuses on standard Italian. Whether and how syntactic doubling operates varies across dialects.

Theoretical models of syntactic doubling

Absalom, Stevens and Hajek (2002) briefly review theoretical models that try to explain why syntactic doubling operates and how. They argue that models based on syntactic constituency (such as a left-branch condition or c-command) fail because syntactic doubling is blocked by a pause between the 2 words, by optional vowel lengthening, by a sudden break in the pitch contour or by inserting a glottal stop

 They suggest that phonologically oriented models based of moras, including some using Optimality Theory may work better.

Absalom, Stevens and Hajek (2002) comment further that all moraic accounts of RS (and therefore Optimality Theory analyses) up to that time assumed that, in Italian:

• all stressed syllables are heavy and are equivalent to two moras (‘µµ) in weight.
• closed syllables are always heavy, eg. /:kan.to/ ⇒ [:kan.to] ‘I sing’, /:fat.to/ ⇒ [:fat.to] ‘fact’
• in word medial position, stressed vowels in open syllables lengthen to satisfy the weight criterion: /:fa.to/ ⇒ [:faù.to] ‘fate’.
• stressed vowels in word-final position are always short in Italian, leaving an empty word-final mora at the word boundary. Italian syntactic doubling fills that empty mora from right to left across the word boundary.

Against those assumptions, Absalom, Stevens and Hajek (2002) argue for further work because:

• some stressed syllables in Italian have more than 2 moras—they are trimoraic (‘µµµ).
• some stressed final vowels are not short and bimoraic.
• stressed final vowels do not automatically trigger syntactic doubling.

Writing

Italian spelling typically does not reflect syntactic doubling when the 2 words are written separately but does show consonant doubling within a word written as a single word.

For example, the verb apprendere (‘learn’) is written as one word, but pronounced in the same way (with [pp]) as a prendere (‘to take’), written as 2 words.
(The verb apprendere was derived historically by prefixing a– (originally ad-) to prendere (‘take’). )

Dictionaries

Some dictionaries mark words that trigger syntactic doubling. For example:

• the online Treccani dictionary marks the preposition da with the abbreviation radd. sint. Da – Significato ed etimologia – Vocabolario – Treccani
• Zingarelli marks them with an asterisk, for example marking the preposition da as da*.
