word-familyword-familyWord FamiliesWord families are groups of words that have a common feature or pattern - they have some of the same combinations of letters in them and a similar sound. For example, at, cat, hat, and fat are a family of words with the "at" sound and letter combination in common.The 37 most common word families in English (according to Wylie and Durrell) are: ack, ain, ake, ale, all, ame, an, ank, ap, ash, at, ate, aw ay, eat, ell, est, ice, ick, ide, ight, ill, in, ine, ing, ink, ip, it, ock, oke, op, ore, ot, uck ,ug, ump, unk.Many of the nursery rhymes contain common word families. You can use these rhymes to teach these letter combinations (and how they are spelled and spoken), having the students sound them out after memorizing the rhyme. You can study one word family a week. Students can use the Little Explorers Picture Dictionary to look for more words that belong to word families.The following is a list of the most common word families in English (from Wylie and Durrell, 1970, plus a few extra word families) and examples of each.Word Familiesackattack back black crack hack Jack knack lack pack quack rack sack snack stack tack track whack adadbadbradcadcladdaddoodadgladhadladmadpadsadageagecageengageragesagestagewageailailfailhailjailmailnailpailrailsailsnailtailwailainbrainchaincomplainexplaingaingrainmainobtainpainplainrainslainSpainsprainstainstraintrainakeawakebakebrakecakefakeflakeJakelakemakequakerakesakeshakesnakestaketakewakealealebaledalegalekalemalepalesalescalestaletalewhaleallallballcallfallgallhallinstallmallsmallsquallstalltallthrallwallamcamclamdamdramexamgramhamjamlamma'amPamramSamscamslamspamswamameblamecamefameflameframegamelamenamesameshametameananbanbrancanclanDanfanflanFranJanJapanmanpanpecanplanranscanankbankblankcrankdankdrankflankfrankHankplankprankranksankshrankspanktankthankyankapcapclapflapgaplapmapnaprapsapscrapslapsnapstraptaptrapwrapyaparafarbarcarczarfargarguitarjarmarparscarsparstartartsarashashbashbrashcashclashcrashdashflashgashgnashhashlashmashrashsashslashsmashatatbatbratcatchatfatflatgnathatmatpatratsatslatspattatthatZack vain tamtramwhamyam spanStantanthanvanzap splashstashthrashtrashvatateabate ate crate date debate fate gate grate hate Kate late mate plate rate relate sate skate state awcawclawdrawflawgnawjawlawpawrawsawslawstrawthawayawaybaybrayclaydaydecaydelaydisplayflaygaygrayhayjaylaymaynayokaypayplayeatbeatcheatcleateatfeatgreetheatmeatneatpeatpleatseattreatwheateeleelfeelheelkeelkneelpeelreelsteelwheeleepbeepcreepdeepjeepkeeppeepseepsheepsleepsteepsweepweepeetbeetfeetfleetgreetmeetsheetsleetstreetsweettweetellbellcelldelldwellfarewellfellhellsellshellsmellspellswelltellwellyellenamenBenchildrendenfengentlemenglenGwenhenmenopenpenthentenwhenwrenyenentaccentbentcentdenteventgentlentrentscentsentspenttentventwentestbestchestcrestjestnestpestquestresttestunrestvestwestzesticediceicemicenicepricericeslicespicesplicethricetwiceviceickbrickchickclickflickkicklicknickpickquickRicksickslickstickthickticktrickwickidebridedecideglidehideprideridesideslidestridetidewidepray quay ray relay replay say slay spray stay stray sway they today tray wayifefife knife life strife wife ightbrightdelightfightflightfrightheightknightlightmightilebilefilemileNilepilerilesmilestiletileillbillchilldilldrillfillfrillgillgrillhillinbinchindinfingingrininkinpininebrinedeclinedefinedinefinelinemineninepineingbringclingflingkingpingringsingslingspringinkblinkbrinkdrinkfinkinklinkminkpinkrinkipblipchipdipdripflipgriphiplipnipitadmitbitfitflitgrithititkitknitoatboatcoatfloatgloatgoatoatstoatthroatockblockclockcockcrockdockflockfrockhockjockogblogbogcatalogclogcogdogfogfroghognight plight right sight slight tight tonight vilewhileillJillkillkrillmillpillquillshrillsillskillspillstillswillthrillthrilltilltrillwillshinskinsinspinthintintwinwinwithinshineshrinesinespineswinetinetwinevinewhinewinestingstringswingthingwingwringzingshrinksinkstinkthinkwinkquipripshipsipskipslipsnipstriptiptripwhipziplitmitpitquitsitskitslitsnitspitsplittwitwitknocklockmocko'clockrockshocksmocksockstockjoglogslogsmogoilboil broil coil foil oil soil okeawokeblokebrokechokejokepokeooboocoogooigloomooshoooodgoodhoodstoodwoodoodbroodfoodmoodoofgoofproofroofspoofoofhoofwoofookbookbrookcookcrookhooklookoombloomboombroomdoomgloomgroomoolcooldroolfoolpoolspoolstooloonballoongoonloonmoonnoonsoonoopcoopdroophooploopscoopsnoopoot (long oo)boothootscootshootoot (short oo)footsootopbopchopcopcropdropflopspoil toil smoke spoke stoke stroke woke yoketoo woozoo nook rook shook tookloom room zoom tool spoon swoon stoop troophop lop mop plop pop prop sop shop stop topore bore chore core fore gore lore more ore pore score shore sore spore store ornadorn born corn forlorn horn morn scorn shorn thorn torn worn otapricot blot bot clot cot dot forgot got hot jot knot lot not plot ought bought brought fought ought sought thought wrought ould could should would ouse douse grouse house louse mouse spouse out about bout clout gout grout out lout pout scout shout snout spout stout tout ow (rhymes with cow) bow cow chow how now plow sow vow wow ow (rhymes with low)bow blow crow flow glow grow low mow row show slow snow sow own brown crown down drown frown gown nightgown town uck buck chuck cluck duck luck muck puck pluck stuck struck truck tuck yuck ug bug dug hug jug lug mug plug pug rug shrug smug snug thug tug ump bump clump dump grump hump jump lump plump pump rump slump stump thump trump un bun fun gun nun pun run shun spun stun sun unkbunk chunk drunk dunk flunk funk hunk junk lunk plunk punk skunk slunk spunkswore tore wore yore potrotshotslotspottottrottrout stowthrowtowsunktrunk。
