Video Transcript

The -ed suffix is added to verbs to indicate the past tense. The ability to understand the past tense meaning of -ed, as well as to hear, read, and spell it, will help students to comprehend a wide variety of text.

An example of an -ed suffix with an unchanging base word can be found in the word entertained.

The suffix -ed can be pronounced three ways: /ed/, as in rented; /d/, as in filled; and /t/, as in jumped.  Be sure to include all three pronunciations of -ed when teaching this concept. 

The -ed suffix occurs more frequently than all suffixes other than -s and -es.
