The suffixes -dom and -some always reduce to a weak schwa: freedom is /ˈfridəm/ and awesome is /ˈɔsəm/. The suffixes -hood and -ship keep their own short vowel: childhood is /ˈtʃaɪldˌhʊd/ and friendship is /ˈfrɛndˌʃɪp/, never with a schwa.
If you remember only one line from this guide, make it this one: "DOM and SOME go weak; HOOD and SHIP stay." Below you will see why the four suffixes split this way, which common words follow each pattern, the few exceptions worth knowing, and the mistakes learners make most often.
The Rule in Short
- -dom sounds like /dəm/: freedom, kingdom, wisdom, boredom.
- -some sounds like /səm/: awesome, handsome, lonesome, troublesome.
- -hood sounds like /hʊd/: childhood, neighborhood, adulthood, likelihood.
- -ship sounds like /ʃɪp/: friendship, leadership, relationship, hardship.
All four suffixes share one important feature: they are stress-neutral. Adding them never moves the stress of the base word. Free has one syllable, and freedom keeps the stress on that same syllable: FREE-dom. Neighbor is NEIGH-bor, and neighborhood is NEIGH-bor-hood. For the bigger picture, see our guide to stress-neutral suffixes like -ness, -ment and -ful.
So the main stress is never on the suffix. The only question is what happens to the suffix vowel, and that is where the four suffixes split into two teams.
Why It Works: The Logic Behind the Split
-dom and -some behave like other weak suffixes
In American English, most unstressed vowels collapse into the schwa /ə/, the short, relaxed "uh" sound. Suffixes are one of its favorite homes. You already hear it in -ful (careful /ˈkɛrfəl/), -ness (kindness /ˈkaɪndnəs/), -less (careless /ˈkɛrləs/) and -man (policeman /pəˈlismən/). The suffixes -dom and -some belong to the same family. Their spelling shows an O, but in speech that O is just /ə/. Read more in the schwa rule for unstressed syllables, and compare it with -man and -men in policeman and policemen, which reduce in exactly the same way.
-hood and -ship keep a short lax vowel
The vowels in -hood and -ship are /ʊ/ (the vowel of good) and /ɪ/ (the vowel of sit). These are short, relaxed "lax" vowels, and English is comfortable keeping them in unstressed syllables. They are already close to the relaxed center of the mouth, so there is little pressure to weaken them further. You see the same behavior in -ing (running /ˈrʌnɪŋ/) and -ish (childish /ˈtʃaɪldɪʃ/): no stress, but no schwa either.
There is a second reason. Hood and ship still feel like independent pieces to speakers, and the suffix often carries a light secondary stress, marked /ˌ/ in dictionaries: /ˈneɪbɚˌhʊd/, /ˈlidɚˌʃɪp/. It is much weaker than the main stress, but it helps protect the vowel. Some dictionaries mark no secondary stress on these suffixes at all; either way, the vowel stays /ʊ/ or /ɪ/.
Pattern Examples
Here are the four suffixes side by side, with three familiar weak suffixes for comparison.
| Suffix | Sound | Examples (US IPA) | What the vowel does |
|---|---|---|---|
| -dom | /dəm/ | freedom /ˈfridəm/, kingdom /ˈkɪŋdəm/, boredom /ˈbɔrdəm/ | Reduces to schwa |
| -some | /səm/ | awesome /ˈɔsəm/, handsome /ˈhænsəm/, lonesome /ˈloʊnsəm/ | Reduces to schwa |
| -hood | /hʊd/ | childhood /ˈtʃaɪldˌhʊd/, neighborhood /ˈneɪbɚˌhʊd/, likelihood /ˈlaɪkliˌhʊd/ | Keeps /ʊ/ (as in good) |
| -ship | /ʃɪp/ | friendship /ˈfrɛndˌʃɪp/, leadership /ˈlidɚˌʃɪp/, scholarship /ˈskɑlɚˌʃɪp/ | Keeps /ɪ/ (as in sit) |
| -ful (compare) | /fəl/ | careful /ˈkɛrfəl/ | Reduces to schwa |
| -ness (compare) | /nəs/ | kindness /ˈkaɪndnəs/ | Reduces to schwa |
| -less (compare) | /ləs/ | careless /ˈkɛrləs/ | Reduces to schwa |
More -dom words
stardom /ˈstɑrdəm/, fandom /ˈfændəm/, martyrdom /ˈmɑrt̬ɚdəm/, wisdom /ˈwɪzdəm/. Wisdom deserves a note: the base word wise has the long vowel /aɪ/, but wisdom has short /ɪ/. The suffix is still a normal /dəm/; only the base vowel changes.
More -some words
tiresome /ˈtaɪɚsəm/, wholesome /ˈhoʊlsəm/, troublesome /ˈtrʌbəlsəm/, quarrelsome /ˈkwɔrəlsəm/, twosome /ˈtusəm/. Two details: in handsome, the D is silent (/ˈhænsəm/), and awesome is /ˈɔsəm/ for some Americans but /ˈɑsəm/ for many others, depending on whether they merge the vowels of caught and cot. Both are normal. What never changes is the weak /səm/ at the end.
More -hood words
brotherhood /ˈbrʌðɚˌhʊd/, parenthood /ˈpɛrəntˌhʊd/, falsehood /ˈfɔlsˌhʊd/, adulthood /əˈdʌltˌhʊd/. Adulthood shows the stress-neutral rule nicely: if you say a-DULT, you say a-DULT-hood. (Some Americans say AD-ult, and then AD-ult-hood; the suffix follows the base either way.)
More -ship words
membership /ˈmɛmbɚˌʃɪp/, citizenship /ˈsɪt̬ɪzənˌʃɪp/, hardship /ˈhɑrdˌʃɪp/, internship /ˈɪntɝnˌʃɪp/. Look closely at relationship /rɪˈleɪʃənˌʃɪp/: the -tion ending is /ʃən/ and the suffix starts with /ʃ/, so you get /n/ followed directly by /ʃ/. Do not add an extra vowel between them. In fast speech, many Americans also drop the D in friendship: /ˈfrɛnʃɪp/.
Exceptions and How to Spot Them
Greek -some meaning "body"
Science words ending in -osome come from a Greek root meaning "body," not from the English adjective suffix. They keep a full /oʊ/ with secondary stress: chromosome /ˈkroʊməˌsoʊm/, ribosome /ˈraɪbəˌsoʊm/. How to spot them: they are technical biology terms, and the part before -some is not an English word you know (chromo, ribo). Compare lonesome, where lone is a normal English word.
"Some" at the beginning of a word
In something /ˈsʌmθɪŋ/, someone /ˈsʌmwʌn/ and somewhere /ˈsʌmwɛr/, some is not a suffix at all. It is the first, stressed part of a compound, so it has the full vowel /ʌ/. The rule in this guide only applies to -some at the end of a word.
A hidden -ship word
Worship /ˈwɝʃɪp/ does not look like a -ship word, but historically it is "worth" plus "ship." It still behaves like one: stress on the first syllable, and the ending keeps /ɪ/.
Common Mistakes for Learners
- A full O in -dom and -some. Speakers of Spanish, Portuguese, Italian and many other languages read the O as a clear /o/: "free-dom," "awe-some" with a round, tense vowel. In American English the ending is a quick, relaxed /dəm/ or /səm/. Think "FREE-d'm," not "free-DOME."
- Stressing the suffix. French speakers in particular tend to put weight on the last syllable: free-DOM, friend-SHIP, child-HOOD. Keep the main stress on the base word and let the suffix follow quietly.
- Long vowels in -hood and -ship. Many learners, including German speakers, say -ship like sheep (/ʃip/) or -hood like who'd (/hud/). Friendship should not sound like "friend sheep." The -hood vowel is the short vowel of good, not food; the -ship vowel is the short vowel of sit, not seat.
- Overcorrecting -hood and -ship to schwa. Once learners discover schwa, they sometimes reduce everything: "child-hud," "friend-shup." These two suffixes keep /ʊ/ and /ɪ/.
- Pronouncing the D in handsome. It is /ˈhænsəm/, which sounds exactly like hansom (an old type of carriage).
Practice
Listen to each word and repeat it. Pay attention to the last syllable: weak /əm/ for -dom and -some, clear /ʊ/ and /ɪ/ for -hood and -ship.
Practice sentences
Read each sentence twice: first slowly, exaggerating the contrast, then at natural speed.
- Freedom and wisdom grow slowly. (FREE-dəm, WIZ-dəm)
- That handsome actor looked awesome on the red carpet. (HAN-səm, AW-səm)
- I spent my childhood in a quiet neighborhood. (CHILD-hʊd, NEIGH-bor-hʊd)
- Their friendship slowly became a relationship. (FRIEND-ʃɪp, re-LA-tion-ʃɪp)
- The old kingdom went through years of hardship. (KING-dəm, HARD-ʃɪp)
- She won a scholarship and an internship in the same year. (SCHOL-ar-ʃɪp, IN-tern-ʃɪp)
Quick Summary
- All four suffixes are stress-neutral: the stress stays on the base word.
- -dom = /dəm/ and -some = /səm/: weak, with schwa, like -ful, -ness and -less.
- -hood = /hʊd/ and -ship = /ʃɪp/: short vowels that stay, like -ing and -ish.
- Exceptions: Greek -osome words (chromosome, ribosome) have full /oʊ/; some- at the start of a word (something) is stressed /ʌ/.
- Avoid "free-DOME," "friend sheep" and "child who'd."
- Memory line: DOM and SOME go weak; HOOD and SHIP stay.
