  1. What is a suffix? • A suffix is a word part that is added to the end of a word. Sometimes it changes the meaning of a word and its part of speech.

  2. Suffix -ed • The suffix –ed is added to verbs (action words) to place the action in the past. (For example: Today I clean, yesterday I cleaned the house.)

  3. Phonics Rules

  4. -ed has three sounds. If a base word ends in the sound /d/ or /t/, adding -ed makes another syllable that says /ed/ and is pronounced as an extra syllable. For example: faintED

  5. Some regular past tense words that say /ed/

  6. -ed says /d/ • If the base word ends in a voiced consonant sound, the ending ed says /d/ (For example: arrive/arrived; waved is pronounced /wayvd/) • The -ed ending is not pronounced as an extra syllable.

  7. Some regular past tense words that say /d/

  8. -ed says /t/ If the base word ends in an unvoiced consonant sound, the ending -ed says /t/ (jumped). Unvoiced consonant sounds are c, ch, f, gh, k, ks, p, s, sh, t...etc– the –ed sound sounds like /t/ and is not pronounced as an extra syllable. (For example: forced – pronounced /forst/)

  9. Some regular past tense words that say /t/

  10. Spelling Rules

  11. Add –ed to a regular verb The most common spelling characteristic of the regular past tense of a verb is that -ed is added to the base form of the verb: for example, opened, knocked, stayed, etc. (Examples of irregular verbs are go, went, gone. We will learn these later).

  12. Rule 1: Words ending with a C-V-C Pattern • One-syllable words: • If the word ends in a CVC pattern, it gets a double consonant + ED. • Examples: • rub – rubbed • stop - stopped • Two-syllable words: • If the stress is on the first syllable, the word only gets one consonant + ED.Examples: • visit – visited • open – opened • If the stress is on the second syllable, the word gets a double consonant + ED.Examples: • refer – referred • admit - admitted

  13. Rule 2: Words ending in E If the word ends in E, simply add D Examples: smile – smiled fine - fined

  14. Rule 3: Words ending in Y Consonant + Y If the word ends in Y, and has a consonant before it, change the y to i and add ed.Examples: study – studied marry - married Vowel + Y If the word ends in Y, and has a vowel before it, simply add ED.Examples: play – played stay - stayed

  15. Rule 4: Other words... Words ending in two vowels + a consonant If the word ends in two vowels + a consonant, simply add ED.Examples: dream -dreamed rain - rained Words ending in a double consonant:If the word ends in a double consonant, simply add ED.Examples: park -parked earn- earned
