Rogue (r)s: the history of intrusive-r

Text box showing: "A bar of soap is better than a spa in Bath."

The study in a sentence

The phenomenon of intrusive-r entered the English language by means of analogy, through the extension of linking-r (as in bar of soap), which started to appear around the same time.

The change in the pattern over time is accompanied by a change in attitudes to people who use it.

The question

Speakers from Scotland, Ireland or North America typically pronounce the <r> in both bar and better, as they speak rhotic dialects of English.  Many southern British English speakers, who are non-rhotic, do not pronounce the <r> in better, where it occurs before a consonant (or a pause). They do, however, pronounce the <r> in bar of soap, where it appears before a vowel. 

Many English speakers also pronounce an /r/ in a spa in Bath , even though there is no written <r>. So spa is pronounced as if it was spar (as in the name of the shop). 

Other examples include: the idea of peace and law and order. 

Do you pronounce an /r/ at the end of the first word in these phrases? 

Like linking-r, intrusive-r only appears when the following word in the phrase starts with a vowel.


An example of analogy:

A (mother) : B (daughter)

X (father) : [?] (son)




Key concept

Why is intrusive-r present in the speech of many English speakers, and where did it come from? 

If the /r/ is not really part of the word, is it 'wrong'?

Methods: Levels of Transcription

There is often a difference between the written form of a word and its pronunciation.

When sociolinguists want to talk about a sound that differs from one accent to another (a variable), they will show the sound inside ordinary curved brackets ( ) as we have done in the title here.

Stage 1: linking-r only. Before a consonant or a pause:	with /r/ "what a dea[r]" versus without /r/ "what an idea". Before a vowel:	with /r/ "dear Amanda" versus without /r/ "the idea of it".  Stage 2: intrusive-r emerges. Before a consonant or a pause:	with /r/ "what a dea[r]" versus without /r/ "what an idea". Before a vowel:	with /r/ "dear Amanda" versus without /r/ "the idea[r] of it".

How does the pattern of language change by analogy work?

Stage 1: the pattern of pronouncing /r/ before a following vowel becomes established for words ending in written <r>.

Stage 2:  The pattern extends by analogy to words containing the same vowels but that don't end in a written <r>. 

The Answer (1)

The emergence of intrusive-r illustrates a common type of language change: change by analogy

For analogy to take place, two conditions must be satisfied:

Are the conditions for analogy met in the case of intrusive-r? 

"Another vice in the cockney pronunciation is the changing of the sound of the last syllables of words ending in ‘ow’, wherever it is not sounded like a diphthong, but like a simple ‘o’, (which is always the case when the last syllable is unaccented) into 'er' - as feller, for fellow - beller, holler, foller, winder, - for bellow,  hollow, follow, window. As also adding the letter ‘r’ to all proper names ending in ‘a’ unaccented, as Belindar, Dorindar, for Belinda, Dorinda."

The Answer (2)

As to whether intrusive-r is wrong, it depends on what you mean by “wrong”.  

In its early days, intrusive-r was the subject of proscription by many grammarians. Nowadays, most people produce intrusive-r without even realising it, nor do most speakers notice it in others. 

Linguists do not usually concern themselves with prescriptive approaches to language, but instead adopt a descriptive approach. This means looking at language in as objective a way as possible, observing, describing and explaining what they see, in the same way scientists do.
