    The -ED Suffix in English

    A suffix is a bound morpheme—the smallest linguistic unit of a language with semantic meaning—that affixes to the end of a word to form English a new word or a new form of the same word. In English, the rule for adding -ed to words applies to the conjugation of regular verbs into both the simple past tense and the past participle. The following sections explain and exemplify the rules for how to pronounce -ed words in English as well as how to spell verbs with the -ed suffix in written English.

    Pronouncing -ED Words in English

    Teaching English language students to pronounce -ed words in English involves learning three simple pronunciation rules. First, if the last sound of the verb is [t]* (t, tt, te) or [d] (d, de), then the -ed suffix is pronounced as [әd] (ed). For example:

    • Base – -ed Suffix – Pronunciation
    • complete – completed – [kәmplitәd]
    • impede – impeded – [Impidәd]
    • need – needed – [nidәd]
    • want – wanted – [wantәd]

    Second, if the last sound of the verb is a voiceless consonant, then the -ed suffix is pronounced as a voiceless [t] (t). Voiceless consonants, which are also called unvoiced consonants, are produced by not vibrating the voice box in the throat. The eight voiceless consonants in English are [p] (p, pe), [k] (k, ck, ke), [s] (s, se, ce), [š] (sh), [f] (f, gh), [θ] (th), [h] (h), and [j] (y). For example:

    • Base – -ed Suffix – Pronunciation
    • ask – asked – [askt]
    • envelop – enveloped – [ɛnvɛləpt]
    • kiss – kissed – [kist]
    • laugh – laughed – [laft]
    • peep – peeped – [pipt]
    • smash – smashed – [smašt]

    Third, if the last sound of the verb is a voiced consonant or vowel, then the -ed suffix is pronounced as a voiced [d] (d). Voiced consonants are pronounced by vibrating the voice box in the throat. The thirteen voiced consonants in English are [m] (m, me), [n] (n, ne), [b] (b, be), [g] (g, ge), [v] (v, ve), [z] (z, ze), [č] (ch), [w] (w), [r] (r, re), [l] (l, ll, le), [ĵ] (j, dge), [ð] (th), and [ŋ] (ng). All English vowels are voiced. For example:

    • Base – -ed Suffix – Pronunciation
    • compare – compared – [[kəmperd]
    • ding – dinged – [diŋd]
    • name – named – [nemd]
    • prescribe – prescribed – [priskraibd]
    • seal – sealed – [siəld]
    • watch – watched – [wačd]

    Writing -ed Words in English

    Teaching English language students the rule for adding -ed to words involves learning six spelling rules. First, if the verb ends with the letter e, then remove the final e and add the -ed suffix to the end of the verb. For example:

    • Base – -ed Suffix
    • agree – agreed
    • deceive – deceived
    • like – liked
    • tie – tied

    Second, if the verb ends with the letter y preceded by a consonant, then change the y to an i and add the -ed suffix to the end of the verb. For example:

    • Base – -ed Suffix
    • apply – applied
    • deny – denied
    • pry – pried
    • study – studied

    Third, if a verb with one syllable ends with a single consonant other than w or y preceded by a single vowel, then double the final consonant and add the -ed suffix to the end of the verb. For example:

    • Base – -ed Suffix
    • drop – dropped
    • hug – hugged
    • pat – patted
    • rub – rubbed

    Fourth, if a verb with two or more syllables in which the final syllable is stressed ends with a single consonant other than w or y preceded by a single vowel, then double the final consonant and add the -ed suffix to the end of the verb. For example:

    • Base – -ed Suffix
    • admit – admitted
    • concur – concurred
    • format – formatted
    • prefer – preferred

    Fifth, if the verb ends with the letter c, then add the letter k followed by the -ed suffix to the end of the verb. For example:

    • Base – -ed Suffix
    • frolic – frolicked
    • mimic – mimicked
    • panic – panicked
    • picnic – picnicked

    Sixth, for all other verbs, simply add the -ed suffix to the end of the verb. For example:

    • Base – -ed Suffix
    • cancel – canceled*
    • need – needed
    • play – played
    • want – wanted

    *Note that the final letter l is doubled in British English even if the stress is on the first syllable of the verb.
