The Spelling Rules for Adding Suffixes:

When do you change the letter y ?
When does the y stay the same ?

You skipped the test.
Rule breakers break the spelling rule

A lot of words follow these rules, but not all. Here are some examples:

ski+ing = skiing
(ski is not an English word, it is Norwegian, so it can have ii)

taxi += ing = taxiing or taxying
(taxi is short for taximeter cab, from the word tax)

1)
ski+ing = skiing
(ski is not an English word, it is Norwegian, so it can have ii)

taxi += ing = taxiing or taxying
(taxi is short for taximeter cab, from the word tax)


2)
day + ly = daily gay + ly = gaily
pay + ed = paid say + ed = said lay + ed = laid

3)
die, tie, lie:
When the suffix is ing, change ie to y: dying, tying, lying

"Thank goodness for Spellzone during this remote learning phase. The site is easy for students to navigate independently and they're really enjoying the activities and spelling games. You get an awful lot for your money with Spellzone. Really reassuring is the very prompt response with helpdesk queries. I've very rarely needed the helpdesk, but when I have, the issue has been addressed and sorted within a very short time."
