Rules for Adding Suffixes:
When do you change the letter y ?
When does the y stay the same?

Teaching point - learning to spell The 'Change Y' rule, part 2:

A) If the suffix is ing or ish, do NOT change the y to i.

English spelling
cry + ing = crying copy + ing = copying baby + ish = babyish
English spelling
English spelling English spelling

This is because English words do not have two i's together -
it wouldn't look right:


B) If there is another vowel just before the y, do NOT change the y to i.

English spelling
play + ed = played donkey + s = donkeys employ + employer
English spelling
English spelling English spelling

Again, it wouldn't look right to have so many vowels together:


Now try these.
Sometimes you have to change the y to i but sometimes the y stays.

Add the suffix to the root word

Type the answer

monkey + s
enjoy + ing
worry + ed
joy + ous
glory + ous
dismay + ed
hurry + ed
moody + ness
jockey + s
berry + s
key + s
healthy + 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.
