What are Vowels and Consonants?

The English Language is created through the different combinations of 44 sounds (phonemes), 20 vowels and 24 consonants. In our written language we refer to the 26 letters of the alphabet as being consonant or vowel letters depending on which type of sound they are representing.

Vowel sounds allow the air to flow freely, causing the chin to drop noticeably, whilst consonant sounds are produced by restricting the air flow.

Vowel sounds are usually (in the UK Education System) split into two main categories based on sound quality:

  • ‘Short’ vowel sounds, due to the short duration of the sound being made. The sound cannot be held onto without becoming distorted
  • ‘Long’ vowel sounds, due to the length of their pronunciation. These can often be held without distorting their sound.

The letters of the alphabet that we normally associate as being the vowel letters are: a, e, i, o and u. The letter ‘y’ is sometimes referred to as an honorary or semi vowel as it is used to replace one of the other vowel letters in words such as: fly, shy, why or my.

All words in the English language have at least one vowel sound in them so the written version must have at least one vowel letter in it.

Consonant sounds are made (produced) when the air flow is being restricted in some way, for example, changes in tongue position resulting in the mouth not opening as wide. This means that the jaw doesn’t drop noticeably, which is different to vowel sounds.

The letters of the alphabet that usually represent the consonant sounds are: b, c, d, f, g, h, j, k, l, m, n, p, q, r, s, t, v, w, x, y, z. 

What is the difference between #phonics and #phonemic awareness?

With the new school year well under way many new parents are being introduced to the world of phonics and all the technical language associated with it. So, we thought we would take this opportunity to demystify some of that technical language.

Phonics is the association of sounds (phonemes) to written alphabet letters (graphemes). For reading (decoding) the phonics coding system is used to convert the written word into sounds. For spelling (encoding) the same phonics coding system is used to covert sounds heard into letters to form written words.

Phonemic awareness is our ability to split words into their smallest sound units (individual phonemes) and to manipulate these sounds through segmentation, blending, substitution, re-ordering and deletion. This is based on what we hear and say, not the written word.

Good phonemic awareness is the vital skill required before phonics can be introduced successfully as a tool for learning to read and spell.

  • Segmentation – being able to split words into their individual sounds, for example ‘cat’ into c-a-t.
  • Blending – being able to blend individual sounds together to say a word, for example d-o-g into dog.
  • Substitution – being able to swap one sound for another in a word, for example swapping the /k,(k)/ sound in the word ‘cat’ with a /h,(h)/ sound to say the word ‘hat’.
  • Reordering – being able to swap the sounds around to create a new word, for example changing the order of the letters in the word ‘cat’ to form the new word ‘act’.
  • Deletion (omission) – being able to remove a sound from a word to create a new word, for example removing the /t,(t)/ sound from the word ‘cart’ to say the new word ‘car’.

These are developed further when phonics is introduced, sound to letter association.

Why Vocabulary Building with your Child is so Important!  

Building your child’s vocabulary is a vital pre-reading skill. This is because schools teach what is referred to as the ‘The Simple View of Reading’(explained on our blog on 28/08/25).

This means that a child decodes the words using their phonics skills and their own vocabulary knowledge to help them understand the text they are reading.

So, for a child to have good reading skills they need to be able to speedily decode unknown words and recognize familiar printed words. And, understand the meaning and grammatical structure of the spoken language and then use this knowledge to understand the printed text.

This means that a child:

• Who does not fully understand the meaning of all the words and/or the grammatical structure of the spoken language (age appropriate) will also be unable to fully understand the printed text; even if they decoded it correctly.

• Whose ability to understand the spoken word is poor will also be unable to understand the printed text; even if they have managed to decode a few words.

Helping your child build their vocabulary is also vital, if they are to continue to develop good communication skills. Talking, explaining, sharing and playing are all important in developing your child’s vocabulary, their understanding of the words meaning in the context of the conversation and the grammatical conventions of our spoken language.
