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.

Add the suffix to the root word

Type the answer

omit + ed
equip + ment
confer + ing
confer + ence
forbid + en
forget + ful
contain + er
benefit + ing
commit + ed
focus + ing
develop + ed
transmit + er

I have just finalised the progress of the year groups and am delighted to see that from December to June 53% of the 98 students using Spellzone have raised their standardised scores to 100 and above.

One of the students has put in a huge amount of effort in completing Spellzone at least 3 times a week since his arrival with us in January. Looking at his scores after the latest GL testing, his standardised score has risen from 99 to 131. This is a truly phenomenal result. I just wanted to share the best result I have ever seen.
