Spelling - Changing 'y' to 'i': Activity 2 Advanced
Sort the examples into two groups
- CHANGE 'Y' TO 'I' GROUP: merry + -ment → merriment, envy + -able → enviable, deny + -al → denial, rely + -ed → relied, defy + -ance → defiance
- KEEP 'Y' GROUP: obey + -ed → obeyed, annoy + -ance → annoyance, betray + -al → betrayal, enjoy + -ment → enjoyment, employ + -able → employable
When do we change y to i and when do we keep it?
- If there is a vowel letter before the y in the base word, we keep the y. So we keep the y in combinations like oy, ey, ay, where the two letters together represent a vowel sound.
- Otherwise, we change y to i.
Did you notice that there are some examples where the same ending behaves differently with different base words?
- betrayal, denial
- obeyed, relied
There are numerous examples which obey the ‘keep y after a vowel letter’ part of this rule: stayed, annoyed, prayed ...
However, there are some exceptions to the rule: day → daily, gay → gaily, pay → paid, lay → laid, say → said
(Note that these are short words. The last three are also irregular because they don't end in -ed, so we just have to know the individual spellings.)
