Learning these consonant digraph sounds will improve your reading, pronunciation, and spelling. These letter combinations are very common. The complication is that their pronunciation is nothing like their individual letter sounds. Look through them, and also notice the most common words they form.
English spelling can be very strange. Sometimes words keep part of the spelling of the language they came from. Often one sound can be written several ways.
The good news is that there are patterns to English spelling. Learn the patterns shown on this page, ESL Phonics , Short and Long English Vowels, and English Vowel Digraphs. Then you should be able to recognize and pronounce most common English words.
Digraphs are letter combinations that make a single sound.
The digraphs listed here make sounds different from the individual letter sounds blended together.
1. CH makes three sounds in English: most commonly /tʃ/: chair, child, church, & catch, march, watch.
It also makes a /k/ sound in words of Greek origin: character,
Christian, chorus, chronological.
Sometimes it has the /ʃ/ (‘sh’) sound in words of French origin like champagne or machine.
