Consonants
A consonant is a sound that is produced by blocking air from flowing out of the mouth with
the teeth, tongue, lips or palate. Consonants may come alone or in clusters but have to be
connected to a vowel to form a syllable.
English has 21 consonant letters, for 24 consonant sounds in most English accents:  H, J,
K, L, M B, C, D, F, G, N, P, Q, R, S, T, V, W, X,  Z and (sometimes Y). The letter ‘y’
produces a consonant sound if at the beginning of a word ‘yellow’ but a vowel sound if at
the end of a word ‘sunny’. 
Consonant Digraphs
Digraphs are two letters that produce just one sound. These are the seven basic consonant
digraphs; ch, ck, th, sh, ph, ng, wh. Yet, some digraphs have more than one pronunciation. 
‘ghosts’ are some digraphs like ‘wr’ and ‘gn’  because the first letter is not pronounced. Let’s
check the list of the digraphs with examples:

Consonant Blends
A consonant blend occurs when two or more consonants are blended together, yet each
sound may be heard in the blend. The most common beginning consonant blends include:
pl, pr, sl, sm, sp and st, bl, br, cl, cr, dr, fr, tr, fl, gl, gr. Blends can also appear at the end of
words. 
What is a Consonant Blend?
Blends are most of the time categorized into r-blends, such as “br” and “cr”, s-blends, such
as “sc” and “sk” and l-blends, such as “bl” and “cl”. There are also blends that include three
consonants. Popular three consonant blends include str, spl, and spr.
Let’s check the list of two letters blends
blends         examples
bl             which make the /bl/ sound as in blend and black 
br             which make the /br/ sound as in bread and brave

Consonant Clusters
Consonant cluster refers to two or more consonants positioned side by side in a word. They
are also called consonant blends. The longest possible cluster in English is three consonant
sounds at the beginning. They can be up to four consonants long at the end of the word.
Three-letter blends                   examples

What Do You Know about Place and Manner of
Articulation of Consonants and Vowels?
Manner of Articulation refers to the “how” of making sounds. There are six different ways or
manners of articulation. Place of Articulation refers to the ‘where’ of pronunciation. It is the
location where sounds are made. Let’s check the below charts that show the manner and
place of articulations of consonants and vowels.
