A spelling pronunciation is the pronunciation of a word according to its spelling rather than its standard or traditional pronunciation. Words that are spelled with letters that were never pronounced or that were not pronounced for many generations have increasingly been pronounced as written, especially since the arrival of mandatory schooling and universal literacy.

If a word's spelling was standardized prior to sound changes that produced its traditional pronunciation, a spelling pronunciation may reflect an older pronunciation. This is often the case with compound words (e.g., waistcoat, cupboard, forehead) and for many words with silent letters (e.g. oftenoften in the American Heritage Dictionary). Sometimes silent letters do not reflect older English pronunciations, but were added to reflect a word's spelling in its language of origin (e.g. victual, rhyming with littlevictuals in the Merriam-Webster Dictionaryvictual in Oxford Dictionaries but derived from Late Latin victualia) or on the basis of erroneous etymologies (island,island in the American Heritage Dictionary scythe).

Spelling pronunciations are often prescriptively discouraged and perceived as incorrect next to the traditionally accepted, and usually more widespread, pronunciation. If a spelling pronunciation persists and becomes more common, it may eventually join the existing form as a standard variant (for example waistcoat and often), or even become the dominant pronunciation (as with forehead and falcon).

Prevalence and causes Many spelling pronunciations occur in languages with historical orthography, such as French and English, although most languages have some non-phonemic spellings..Even Finnish, where spelling is largely phonemic, has exceptions, e.g. sydämen, ruoan, onko, konepaja, osta paljon, osta enemmän (phonemic spelling would be: sydämmen, ruuan, ongko, koneppaja, ostap paljon, osta 'enemmän), and many words borrowed from other languages. This is especially true for people who are only taught to read and write and who are not taught when the spelling indicates an outdated (or etymologically incorrect) pronunciation. In other words, when many people do not clearly understand where spelling came from and what it is (a tool for recording speech, not the other way around), spelling pronunciations are common.

On the other hand, spelling pronunciations are also evidence of the reciprocal effects of spoken and written language on each other.Michael Stubbs, Language and Literacy: the Sociolinguistics of Reading and Writing. London: Routledge & Kegan Paul, pp. 31-32. Many spellings represent older forms and corresponding older pronunciations. Some spellings, however, are not etymologically correct.

Speakers often privilege spelling pronunciations. Pronunciations can then arise that are similar to older pronunciations or that can even be completely new pronunciations that are suggested by the spelling but never occurred before.

English examples kiln with a fully pronounced n, instead of a silent n. Kiln was originally pronounced kil with the n silent, as documented in Webster's Dictionary of 1828.

Older dictionaries do not list the pronunciation with although the 2nd edition of the OED does (and the first edition notes the pronunciation with the comment that it is prevalent in the south of England and often used in singing; see the Dictionary of American Regional English for contemporaneous citations that discuss the status of the competing pronunciations). The sporadic nature of such shifts is apparent upon examination of examples such as whistle, listen and soften in which the t remains usually silent. forehead once rhymed with horrid but is now pronounced with the second syllable as by 85% of American speakers and 65% of British speakers.

Borrowings When English borrows words from other languages, it usually keeps the original spelling, and they are often pronounced according to English conventions:

Italian maraschino, bruschetta pronounced with rather than ; Italian pistachio (Italian spelling pistacchio) pronounced with (or with , as if it were a French word) rather than ; French hotel (French spelling hôtel, with silent h) pronounced with .

Opinions

Spelling pronunciations give rise to varied opinions. Often, those who retain the old pronunciation consider the spelling pronunciation to be a mark of ignorance or insecurity. Those who use a spelling pronunciation may not be aware that it is one and consider the earlier version to be slovenly since it slurs over a letter. Conversely, the users of some innovative pronunciations such as (for February) may regard another, earlier version as a pedantic spelling pronunciation.

Henry Watson Fowler (1858–1933) reported that in his day, there was a conscious movement among schoolteachers and others encouraging people to abandon anomalous traditional pronunciations and to speak as is spelled. According to major scholars of early modern English (Dobson, Wyld et al.), in the 17th century, there was already beginning an intellectual trend in England to pronounce as is spelled. That presupposes a standard spelling system, which was only beginning to form at the time. Similarly, quite a large number of corrections slowly spread from scholars to the general public in France, starting several centuries ago.Peter Rickard, A History of the French Language (1989).
