Adding Suffixes to Longer Words

Teaching point - learning to spell Two more things to think about:

1) Sometimes the suffix changes the meaning of a word so that the stress falls on a different syllable. In these words the stressed syllable is in colour. See how it affects the doubling of the last letter:

English spelling
prefer: I would prefer to stay in tonight.
preferred: She preferred the pink dress to the blue one.
preference: He has a preference for classical music.
English spelling
English spelling English spelling

In preferred, the stress is on the second syllable - preferred -
so we must double the r.

In preference, the stress is on the first syllable - preference -
so we do not double the r.

2) Long vowel sounds and those spelled with two letters do not need protection:

English spelling
remain + ing = remaining avoid + ance = avoidance
English spelling
English spelling English spelling

Now try these. Remember the rule:
Double the consonant if
a) the syllable just before the suffix is the stressed syllable and
b) you do not already have enough consonants to protect the vowel sound.
