About this word list ▲
When adding a suffix to a word, you don’t always need to double the final letter. For example, doubling is not required if a word ends with two consonants, as in crafty, or if the suffix begins with a consonant, as in thankless.
This rule helps make spelling simpler by limiting unnecessary letter repetitions. Words that follow this pattern include everyday examples like checked and locked.
This list provides a variety of words to explore, each illustrating how the doubling rule works in different contexts.
