Adding suffixes to longer words

So, remember, with our longer words, we only double the consonant if the syllable before the vowel suffix is stressed. Look at these examples:

English spelling
begin + er = beginner forget + ing = forgetting
equip + ed = equipped regret + ing = regretting
English spelling
English spelling English spelling

We don’t need to double it in these words, because there is an unstressed syllable before the suffix:

English spelling
open + ed = opened rocket + ed = rocketed
alter + ing = altering edit + or = editor
English spelling
English spelling English spelling

And a final reminder that if we are adding a consonant suffix, or the root word ends in two consonants, we don't double either:

English spelling
attend + ed = attended reform + er = reformer
desert + ing = deserting result + ed = resulted
English spelling
English spelling English spelling

Now try these:

Add the suffix to the root word

Type the whole word:

admit + ing
begin + ing
open + ing
transmit + ed
blossom +ed
garden + er
regret + ing
submit + ed
upset + ing
gallop + ed
occur + ing
perform + er

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.
