Rules for Adding Suffixes (-ed)

Let’s look at the different rules for adding suffixes to root words. The suffix -ed is a vowel suffix, so there are some special rules to follow when adding vowel suffixes. The -ed suffix usually changes words to past tense.

Rule 1: If the verb ends with two consonants, we keep the spelling, and add -ed. For example, walk ends in two consonants, so add the -ed suffix to make the word walked.

Rule 2: If a verb ends in a short vowel sound and a single consonant, double the final consonant and add -ed. For example, hop has a short vowel sound and a single consonant, so double the final letter and add -ed, to make the hopped.

Rule 3: When a verb ends with silent e and the suffix begins with a vowel, drop the e and add the suffix. For example, use ends with a silent e, so drop the e and add -ed to make the word used.

Rule 4: When a word ends with a vowel before y, keep the y and add -ed. For example, enjoy ends with a vowel before the y, so add -ed to make the word enjoyed.

Rule 5: When a verb ends in a consonant then y, replace the y with an i, then add -ed. For example, carry ends with a consonant then y, so replace the y with an i, and add -ed to make the word carried.

Transcript Adding Suffixes to Base Words (-ed)

"Hello Grandma!" "We have so much to tell you about our weekend!" "Wait... Koko, how do we explain what we did?" Let's help Koko and Pip learn about adding suffixes to base words. Suffixes are word parts that are added to base, or root, words that can change the meaning. Today, we will be learning about a suffix that can change verbs from present tense to past tense. This suffix is -ed. Let's look at the rules for this suffix! If the verb ends with two consonants, we keep the spelling, and add -ed. For example, walk ends in two consonants, so add -ed to make the past tense, walked. What about the word, jump? Jump ends with two consonants so add -ed to make the word, jumped. Here is the next rule: When a verb ends in a short vowel sound and a single consonant, double the final consonant and add -ed. For example, hop has a short vowel sound and a single consonant, so double the final consonant and add -ed to make the past tense, hopped. What about the word, plan? Plan has a short vowel sound and a single consonant, so double the final consonant and add -ed to make the past tense, planned. Here is the next rule: When a verb ends with a silent e and the suffix begins with a vowel, drop the e and add the suffix -ed. For example, use has a silent e, so drop the e and add -ed to make the past tense of the verb, used. What about the word, excite? Excite has a silent e, so drop the e and add -ed to make the past tense, excited. Here is the next rule: When a verb ends with a vowel before y, keep the y and add -ed. For example, enjoy ends with a vowel then a y, so keep the y and add -ed to make the past tense, enjoyed. What about the word, stay? Stay ends in a vowel then a y, so add -ed to get the past tense, stayed. Here is the final rule: When a verb ends in a consonant then y, replace the y with an i, then add -ed. For example, the verb carry ends in a consonant then y, so replace the y with an i, then add -ed to make the past tense verb carried. What about the word, reply? Reply has a consonant then a y so replace the y with an i, then add -ed, to make the past tense, replied. While Koko and Pip tell Grandma all about their weekend, let's review! Remember, verbs can be changed to past tense by adding the suffix -ed. We can follow special rules such as these, these, and this one! “So we walked to the park. Then we went to the store where we shopped! We used all of our gift cards." "We really enjoyed our day, and we carried everything home!" "Koko... we were on mute the whole time!"
