Common Suffixes: Recognize Word Endings and Grammar
Learn common English suffixes and use them to predict part of speech, meaning, spelling, and possible anagrams.
Suffixes provide grammatical clues
A suffix attaches to the end of a base word. It can change tense, number, part of speech, or meaning. Recognizing a likely ending often reduces a difficult letter set to a manageable root.
| Suffix | Typical role | Examples |
|---|---|---|
| -s / -es | Plural or third-person verb | cats, watches |
| -ed | Past tense or participle | walked, formed |
| -ing | Participle or gerund | running, making |
| -er | Person, object, or comparison | writer, faster |
| -ly | Often forms an adverb | quickly, softly |
| -ness | State or quality | kindness, darkness |
| -tion | Action or result noun | action, creation |
| -able | Capable of | readable, washable |
| -ment | Result or process | movement, agreement |
| -ful | Full of | helpful, careful |
Use endings to narrow anagrams
If a rack contains I, N, and G, test -ing and examine the remaining letters for a verb stem. Do the same with -ed, -er, or plural -s. Do not force an ending when the leftover letters cannot form a valid root.
Expect spelling adjustments
Adding a suffix may double a consonant, drop a final E, or change Y to I. These rules matter in spelling practice and when evaluating candidate words.
