Correct spelling for the English word "intrusive r" is [ɪntɹˈuːsɪv ˈɑː], [ɪntɹˈuːsɪv ˈɑː], [ɪ_n_t_ɹ_ˈuː_s_ɪ_v ˈɑː] (IPA phonetic alphabet).
The term "intrusive r" refers to a phonological phenomenon in certain English dialects, particularly in the United States, where the letter "r" is pronounced even when it is not indicated in the spelling. This phenomenon, also known as "rhoticization," involves the intrusive addition of the "r" sound in specific environments and positions within words.
Intrusive r most commonly occurs in dialects that exhibit non-rhotic pronunciation, a feature found in British English and some regional accents. In these dialects, the r sound is typically absent at the end of words or before consonants, resulting in pronunciations such as "caah" for "car" or "lettah" for "letter". However, in the case of intrusive r, the r sound is inserted where there was historically no r, typically at the end of a word before a vowel sound, or before another word beginning with a vowel sound.
The intrusive r phenomenon can be seen in phrases like "law and order," which may be pronounced as "lawr and orderr" or "soda and ice," pronounced as "sodar and ice." The intrusive r is often perceived as a prominent feature of certain American English accents, particularly in the Northeastern and Mid-Atlantic regions, including the famous "Boston accent."
The intrusive r can sometimes be mistaken for a linking r or a deliberate addition of the r sound by non-native speakers, but it is actually a natural occurrence in specific dialects of English. It is important to note that not all English dialects exhibit this intrusive r, and its occurrence can vary depending on regional and individual linguistic factors.
The term "intrusive R" refers to a phenomenon in certain accents or dialects of English, where an "R" sound is inserted into certain words or positions where it is typically not pronounced. This linguistic feature can notably be found in some regions of England, Scotland, Ireland, and parts of the United States.
However, it's important to note that "intrusive R" is not a word in itself, but rather a description of a specific type of pronunciation. As such, it does not have a specific etymology.
The "intrusive R" sound is believed to have developed as speakers adapted their pronunciation over time. In many cases, it occurs at the end of a word ending with a vowel sound, followed by a word beginning with a vowel sound. The inserted "R" can help provide a smoother transition between words and improve overall speech flow.
