Before we get into words with one vowel, let us know about the English Alphabet first.

The present English alphabet consists of 26 letters, each of which has an upper- and lower-case version. It was derived from Latin script in the 7th century. Letters have been added or removed since then, resulting in the current Modern English alphabet, which consists of 26 letters with no diacritics, digraphs, or special characters. The Greek alphabet’s first two letters, alpha and beta, are combined to form the word alphabet.

Evolution of the English language

With waves of attack and eventual occupation by the Angles, Saxons, Jutes, and Frisians, the evolution of spoken English began in the fifth century. They spoke the same West Germanic language, but their dialects were different. Their mingling resulted in the creation of a new Germanic language known as Anglo-Saxon, or Old English.

The Vikings raid and settle in the eighth, ninth, and tenth centuries, bringing with them a different dialect of the same Germanic language, now known as Old Norse. The fusion of English and Viking would be the second phase in forming spoken English, and the foundation for today’s diverse English dialects.

Further vowel alterations occurred during the Middle English period. The Great Vowel Shift (c. 1500 CE) was the most profound, transforming the sound of all long vowels. The considerable changes in pronunciation between “short” mat, met, bit, cot vs. “long” mate, mete/meet, bite, coat happened after the spelling system was fixed. Other changes that left echoes in modern language include homorganic lengthening before ld, mb, nd, which accounts for the long vowels in child, mind, climb, and other words; pre-cluster shortening, which accounts for vowel alternations in child vs. children, keep vs. kept, meet vs. met; and trisyllabic laxing, which accounts for alternations such as grateful vs. gratitude, divine.

The emergence of rhotic and non-rhotic accents (i.e. “r-dropping”), the trap-bath split in many dialects of British English, and the flapping of t and d between vowels in American and Australian English are among the more notable recent modifications to the language.

Vowels

A vowel is a syllabic spoken sound that is pronounced without any vocal tract stricture. Vowels are one of the two main types of speech sounds, with consonants being the other. The quality, loudness, and number of vowels varies (length). They are usually voiced and play an important role in prosodic variation like tone, intonation, and emphasis.

The word vowel is derived from the Latin word vocalis, which means “to speak” (i.e. relating to the voice).

The word vowel is frequently used in English to refer to both vowel sounds and the written symbols that represent them (a, e, i, o, u, and sometimes y).

The phonological definition of “vowel” may not always match the phonetic definition (i.e. a sound produced without constriction in the vocal tract) (i.e. a sound that forms the peak of a syllable). The approximants [j] and [w] show this: both have little constriction in the vocal tract (thus phonetically they appear to be vowel-like), but they occur at the beginning of syllables (e.g., in “yet” and “wet”), implying that they are consonants phonologically. In rhotic dialects, there is a similar controversy over whether a word like bird has an r-colored vowel / or a syllabic consonant /.

Consonant

A consonant is a sound that is not a vowel in speech. It also refers to the letters of the alphabet that represent certain sounds: consonants include Z, B, T, G, and H.

All non-vowel sounds, or their equivalent letters, are consonants: A, E, I, O, U, and occasionally Y are not consonants. H and T are consonants in hat. A consonant can also be used as an adjective to indicate things that appear to be compatible, or things that are “agreeable.” You may remark that a country’s aid offer is in line with its treaties. Consonant sounds are pleasant to hear in music, as opposed to “dissonant” sounds, which are unpleasant.

Linguists have invented systems such as the International Phonetic Alphabet (IPA) to assign a unique and unambiguous symbol to each confirmed consonant because the number of speech sounds in the world’s languages is significantly greater than the number of letters in any one alphabet. Because there are fewer consonant letters in the English alphabet than there are consonant sounds in the English language, digraphs like ch, sh, th, and ng are employed to extend the alphabet, however some letters and digraphs represent more than one consonant. For example, the sound spelt th in “this” is not the same as the sound spelled th in “thin.
