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.

SuffixTypical roleExamples
-s / -esPlural or third-person verbcats, watches
-edPast tense or participlewalked, formed
-ingParticiple or gerundrunning, making
-erPerson, object, or comparisonwriter, faster
-lyOften forms an adverbquickly, softly
-nessState or qualitykindness, darkness
-tionAction or result nounaction, creation
-ableCapable ofreadable, washable
-mentResult or processmovement, agreement
-fulFull ofhelpful, 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.
