The Spelling Rules for Adding Suffixes:

When do you drop the letter e ?

think back to spelling teaching

Remember, a suffix is a letter or group of letters added to the end of a root word to change its meaning.

A vowel suffix is a suffix that begins with a vowel.


Teaching point - learning to spell

If you are adding a vowel suffix to a word that ends in e, drop the e.

For example:


word lists word lists
date + ing = dating froze + en = frozen shine + y = shiny
word lists word lists

When do you keep the letter e ?

Teaching point - learning to spell

A consonant suffix is a suffix that begins with a consonant.

If you are adding a consonant suffix to a word that ends in e, you do not need to drop the e.

For example:


word lists word lists
hope + less = hopeless wise + ly = wisely tune + ful = tuneful
word lists word lists

The e at the end of words makes the first vowel sound long. For example, the e in the word hope stops it from sounding like the word hop.

If we removed the e when adding a consonant suffix, there would be nothing to do the important job of making the long vowel sound.

Let’s try it by adding the suffix -less:

If we take away the e, we would pronounce our new word hop-less. This has a very different meaning to the word hope-less!

Can you use the above rule to work out when you need to drop the e and when you don’t?

For every spelling rule, there are some rulebreakers.
