What is a Consonant?

Part Two in this week's Vowels, Consonants, and Syllables series!

In yesterday's blog post, I discussed the often misunderstood question "what is a vowel?" and why it is helpful to teach students an accurate definition rather than a memorized and oversimplified list. That brings us to today's question: What is a consonant?

A consonant is a sound that is blocked by the tongue, teeth, or lips.

Most consonants cannot be controlled for volume and cannot be sustained. Any sound that is not a vowel - a sound that can be sung and sustained with the mouth open - is a consonant. English has 26 consonant sounds, and we write them in 38 different ways in common English words.

Consonant Sounds and Spellings

In our curriculum and materials, Logic of English® teaches students the definition of a consonant and a vowel, which enables them to test each sound and determine for themselves which kind it is. For example, from Foundations Lesson 26, while learning the phonogram n:

Teacher: Can you sing the sound /n/?
Students: Nnnn... yes.
But is something blocking the sound? Nnnn... My tongue is blocking the sound.
Plug your nose and try to say /n/. Where is the air coming out? My nose.
Is /n/ a vowel or a consonant? Consonant.
Why? My tongue is blocking the sound. A vowel is a sound that is open and not blocked.

In addition to saving students the time it would take to memorize lists of letters by rote, this approach also gives them a linguistically accurate understanding of consonants on which they can build future literacy skills.

When you know the definition of a consonant, it is much easier to master the concept of syllables! And these combined skills then equip students for greater success in spelling and decoding.
