C and G

The consonants c and g make a soft sound (s and j) when they are followed by e, i or y.
Remember these phrases: city centre cyclist; gentle giant in the gym.
This rule becomes important when suffixing because you need to make sure that you keep the c or g soft by keeping the e: manageable, noticeable. You can drop the e when an i does the work: managing, noticing.

Some words have a u to stop the e making the g soft: guest, league.
Some words with a sh sound change the e to i: vicious.
