It'ssomethingvery importantforyoutolearn.

Solet'stalkaboutwhatit meansandhowweuseit.

So,weuse:"incase"or"justincase"-weuse both-whenwearetalkingaboutdoingsomething

topreventaproblem.

Okay?

Sowe'retalkingabout...

Ordoingsomethingto prepareforaproblem.

So,we'relookingataproblemandwe'relooking atpreparationorpreventionofthatproblem.

Okay?

So,forexample:"Tonight,I amgoingtoarestaurant."

I'mveryexcited.

Now,theproblemisIgetcoldveryeasily, andwhenI'mcoldI'mnotaveryniceperson;

Igetverycranky,andI'mnotagood persontobewithwhenI'mcold.

SomyproblemisI getcoldeasily.

Whatismypreventionor preparationforthisproblem?

Well:"Iwillbringasweater justincaseIgetcold."

Okay?

AndthatwayIwillhaveagreat timeattherestaurant,hopefully.

Somyproblemisbeingcold,andmy preparationisI'mgoingtobringasweater.

So,asyoucansee,ifyouthinkaboutlife, wehavealotofthesetypesofproblemsand

wedoalotofthingstoprepare forthesetypesofproblems.

Solet'slookat someotherexamples.

Okay,aproblemis whenitrains...

Okay?

Alotofthetimeswhenitrains,youknow, Idon'tlikegettingwet,sowhatdoIdo?

Well,mypreparationorpreventionisIbring anumbrella,ormaybeI'llbringarainjacket.

Okay?

So:"Iwillbringanumbrella justincaseitrains."

Anotherproblemisifyouworkat9am,you know,alotofthetimesthere'salotof

cars;everybody'sgoingtoworkatthe sametime,there'salotoftraffic.

Andifthere'salotoftraffic maybeyou'llbelateforwork.

Sowhatwillyoudo forthisproblem?

So,trafficistheproblemormaybegoing toworklateistheproblem,butwhatyou

candotopreventorprepareforthis problemisyoucanleaveyourhouseearly.

So:"Ileavemyhouseearlyevery dayjustincasethere'straffic."

Anotherexampleofaproblemismaybeyou're goingtovisityourfriend,andyourfriend

givesyoutheiraddress.

Now,ifyoudon'twritedowntheir address,you'regoingtobelost.

Idon'tknowwheretheylive.

Ineedtogotomyfriends'house,Iforget theiraddress;Idon'tknowwheretheylive.

Sothisistheproblem.

Especiallyifyou'reveryforgetfullikeme oryoualwaysforgetpeople'sphonenumbers

or,youknow,wherepeople live,thisisabigproblem.

Sowhatdoyoudoto preventthisproblem?

Well,youwrite downtheiraddress.

Okay?

Onapieceofpaper,yourfriendtells youtheiraddress,youwriteitdown.

Whydoyouwriteitdown?

"Youwritedowntheiraddress justincaseyouforgetit."

Okay?

Youforgettheiraddress.

SoI'vejustgivenyousomeexamples ofwherewewoulduse"justincase".

Therearealotofexamples for"justincase".

Iwantyoutothink aboutyourlife.

Istheresomethingthathappenseveryday toyou,maybeyouhavesomesortofproblem

orsomethingyouworryabout?

Sothinkabout thatforasecond.

Istheresomethingyouworryabouteveryday, andwhatdoyoudotoprepareforthator

topreventaproblem fromhappening?

Okay?

Maybe,youknow,you'reworriedaboutfailing yourtest,soyoumightcreateastudygroup

justincase.

Okay?

Ormaybe,youknow,your teachergivesyouhomework.

Maybeyouwilldothehomework justincasetheywanttoseeit.

So,youseewhatI'msaying?

There'salotofproblemsyoumighthave,and alotofpreventionsorpreparationsyou

doforthoseproblems.

Sotrytothinkofone inyourownlife.

Okay,sonowwearegoingtolookatthe grammarof"justincase"or"incase".

Okay,sowe'vealreadylookedatwhatare problems,andhowweprepareorpreventproblems.

Nowlet'slookatsomeexamplesof:Howdowe createthissentenceinagrammaticalfashion?

So,Ihaveherethesentence:"Iwill bringanumbrellaincaseitrains."

Doyourememberwhat theproblemis?

Theproblemisitrains,andthe preparationisbringinganumbrella.

Ihaveanothersentence.

"Iwillleavemyhouseearly incasethereistraffic."

So,again,trafficistheproblem,andleavingmy houseearlyisthepreparationortheprevention

ofaproblem.

So,Ihaveacoupleofquestions foryouaboutthegrammar.

Okay?

Iwantyoutolookatthesentences,both ofthesesentences:Istheproblem...?

Sotheproblemwe'retalkingabout,doyousee theproblembeforeoraftertheexpression

"incase"?

Sowhereistheproblem?

Sowefind"incase".

Istheproblembefore"incase",uphere; oristheproblemafter"incase"?

It'safter,right?

So,"itrains"istheproblem,so:"in caseitrains",thesegotogether.

Whataboutdownhere?"...incase",isthe problembeforetheword"incase"orisit

aftertheword"incase"?

Well,theproblemistraffic,sothe problemcomesaftertheword"incase".

Okay?

Soifithelpsyouto remember:"incase"...

Sowewouldn'twrite thisinasentence.

Thisis...

Wewon'tputthesebracketsinasentence,but justtohelpyouinyourheadtoremember:

"incase"iswiththeproblem,sothese arelikeoneunit,ifthatmakessense.

Okay.

Andsoiftheproblemcomesafter"in case",whatcomesbefore"incase"?

Thepreparationor theprevention.

Soafter"incase"istheproblem,before isthepreventionorthepreparation.

Okay,sowhatverbtense comesafter"incase"?

Sowhenwe'retalkingabouttheproblem,whatis theverbtensethatweusewhenwe'retalking

abouttheproblem?

SoIwantyoutolook,here'sthe verbandhereistheotherverb.

Isthisthepast,the present,orthefuture?

Ifyousaidthepresent, youarecorrect.

Weusethepresenttense whenweuse"incase".

Okay?

Andso:"incaseitrains", wecouldputthis...

Youknow,imagineifIsaid:"Iwillbringa sweaterincaseitgetscold",sothepart

after"incase"isalways inthepresenttense.

Okay.

Soanotherquestionyoumightbewondering: "Do'incase'and'justincase'meanthe

samething?

CanIuseeither,'in case'or'justincase?'"

"Iwillbringanumbrellajustincaseit rains"or"incaseitrains",they'reboth

correct.

It'syourchoice;youcanuse whicheveroneyouprefer.

Okay,andthesetwosentencesusetheword "will":"Iwillleavemyhouseearly","I

willbringanumbrella",sothisistalking about,youknow,doingsomethinginthefuture,

right?

"InthefutureIwillbringanumbrella",or "InthefutureIwillleavemyhouseearly".

Dowealwaysuse "will"whenweuse...?

Whenwe'remakingthese typesofsentences?

CanIsay:"Ialwaysbringanumbrellain caseitrains"or"Ibroughtanumbrellain

caseitrains"?

CanIusethepast,present,or future,orisitalwaysthefuture?

Actuallyfor"justincase",youcanuse"will", youcanusethepasttense,oryoucanuse

thepresenttensewhenyou're talkingaboutthepreparation.

Sotheproblem...

We'retalkingaboutafutureproblem,this staysinthepresenttense;butintermsof

thepreparation,itdependson whenyoudothepreparation.

Sothekeyquestionhereis:Whendidyou prepare,orwhendidyoupreventtheproblem?

SoI'llgiveyousomeexamples.

Imagineforthisone:YesterdayIbrought anumbrellatoworkbecausetodayIknewit

wouldrain.

Soifinthepast,ifyesterdayorearlier today,youknow,Ibroughtanumbrella,we

couldchangethisto:"brought".

"Ibroughtanumbrella incaseitrains".

"...incaseitrains" staysthesame.

Okay?

It'salwaysinthepresent.

Butbeforethepreparation wecanusethepast.

Orwhataboutif,youknow...

Forexample,thesecondsentence,imagine Ialwaysleavemyhouseearly,everyday.

Okay?

Ialwaysdoit.

It'saroutine.

"Iwillleavemyhouseearly incasethere'straffic."

Ifit'saroutineanditalwayshappens,I canusethepresenttensehere,Icansay:

"Ialwaysleavemyhouseearly incasethereistraffic."

Okay?

Orifwe'retalkingaboutsomethingI'lldo inthefuturetoprepare:"Iwillleavemy

houseearlyincase thereistraffic."

So,bottomline,thekeypointhere,thething thatyoureallygottoremember:After"in

case"thisis alwaysthepresent.

Okay?

So,afterthewords"incase",theverbis thepresent;butwhenyou'retalkingabout

whatyou'redoing,thepreparation, itdependsonwhenyouprepare.

Ifyou'repreparing...

Iftheactionofpreparingisinthepast, youusethepast;ifit'saroutinethatyou

alwaysdo,youusethepresent;orifit's somethingyou'regoingtodo,usethefuture.

Okay?

SoletmethinkifIcan giveyouanotherexample.

Okay,ifwethinkaboutatestandstudying,I cansay:"Istudiedhardformytestyesterday

incasemytestishard."

Or,sorry:Istudied...

Yeah.

"Ireallystudiedformytestyesterdayin casethetestishard",sowehaveitinthe

past,Istudiedinthepast.

Nowif,youknow,maybeIalwaysstudyfor atestandIalwaysreallystudyhardfor

atest,Icansayitinthepresent:"I alwaysstudyforatestincaseit'shard."

Or,youknow,maybeI'veneverdonethatbefore, butmaybetomorrowI'mgoingtostudy,Ican

say:"Iwillstudy,youknow, formytestincaseit'shard."

Okay?

Soitdependsonwhen you'redoingthataction.

Allright,sowe'regoingtolookatacouple moreexamples,youknow,togetyoumorepractice

andmorefamiliarwith"in case"and"justincase".

Okay,soinmylife Igethungryalot.

AndjustlikewhenIgetcoldI'mnotreally ahappyperson,whenIgethungryI'mnot

ahappyperson.

SoinordertomakesureIstayhappy, Ialwaystrytohavefoodwithme.

So,forexample,I'vemadeasentencewith "justincase"or"incase":"Ibroughta

sandwichtodayin caseIgethungry."

Sowhat'stheproblemhere?

TheproblemiswhenEmma'shungry she'sahorriblepersontobearound.

Okay?

So,wehaveaproblem: Emma'shungry.

So,whatdowedotomakesureEmma, youknow,stayslikeahappyperson?

Well,wemakesureshetakesasandwich withher,sothat'sthepreparation.

Okay?

And,again,after"incase"wehavethe problem,beforewehavethepreparation.

Okay,andthis,again, isinthepresenttense.

Andthisoneisinthepasttense becauseIalreadybroughtthesandwich.

Okay?

ThisissomethingI didthismorning.

Now,itispossibletochangethe structureofthesentencearound.

Youdon'thaveto,soifyouthink:"Wow, Emma,todayIlearnedalot,Idon'twant

to,youknow,learnanymore", that'sokay,you'velearnedalot.

Butifyou'reinterested,wecanalsochange thesentenceandputitintheoppositeway.

SowhatdoImeanbythat?

Well,inthiscase"incase"isthesecond partofthesentence;wecanalsoputitas

thefirstpartofthesentence.

"IncaseIgethungry,"-soit'stheexact samewords,wejustaddacomma-"Ibrought

asandwich".

Soit'syourchoice,they havetheexactsamemeaning.

Youcanstartwith"Incase"or"incase" canbeinthemiddleofthesentence.

Butwhenyoustartwith"Incase", justmakesureyourememberthecomma.

Upherethere'snocomma.

Okay?

So,foralotofpeoplethisiseasierbecause they,youknow,forgettheircommas,butwe

douseboth.

Okay,let'slookat anotherexample.

"Ialwayskeepmedicineat homeincaseI_______sick."

Okay?

Soifyouthinkaboutit,alotofpeople willhavemedicineforheadaches,orforwhen

theycatchacold,they keepmedicineathome.

Sowhat'stheproblemhere?

Theproblemisgettingsick.

Okay?

So,theproblemisgettingsick, andhowdoweprepareforthat?

Well,wehavemedicineathome.

So,after"incase"Iwant tousetheverb"get"here.

WhatdoIneedtodo totheverb"get"?

Isitgoingtobeinthepasttenseas in"got",doIsay"get",or"willget"?

WhattensedoIuse?

Ifyousaid"get",whichisthe presenttense,youarecorrect.

Yay.

Goodforyou.

Ihopeyougotthat.

"Ialwayskeepmedicineat homeincaseIgetsick."

And,again,thisisinthepresentbecauseit's somethingwedoasaroutine,we'realways

doingthis.

Okay,sothelastexample:"I'llgo earlyjustincasethereisaline."

Soimagineyou'regoingtothemovietheatre, andyouknowalotofthetimeswithmovie

theatresthere'salong lineup-that'saproblem.

Alonglineupisaproblem,sowhatdoyou dotopreventthatproblemortopreparefor

it?

Well,yougotothemovietheatreearlyso youcanlineupandmakesureyougetagood

seat.

So,inthiscaseI'veused theword"justincase".

"I'llgoearlytothemovietheatre justincasethereisalongline."

DoIneedtouse, like,allofthis?

CanIjustsay:"I'llgoearlyjust incase",andnotevensaythis?

That'spossible.

Soifyoudon'tevenwanttodothis,you canactuallyjustsay:"I'llgoearlyjust

incase"aslongasthepersonyou'retalking toknows,like,thecontextandcanunderstand

whatyou'retalkingabout,andit'sobvious, youknow,whatyou'redoing,youcanjust

use"justincase"instead ofthefullsentence.

Okay?

So,evenuphere:"Ialwayskeepmedicineat home",youprobablykeepmedicineathome

inorder...

Like,incaseyougetsick,it'skindofobvious, soifyouwantedto,youcanjustsay:"...just

incase".

Okay?

Sothere'sacoupleofways wecanuse"justincase".

You'velearnedacouple ofdifferentwaystoday.

Youwillhearallofthesedifferent variationsinconversation,inmovies,onTV.

Again,"justincase"and"incase"isvery commonandveryimportant;weuseitalot.

Soyoumighthearanyof thesevariationsofit.

So,Ihopeyouhave enjoyedthislesson.

Andjustincaseyouwanttopracticemore,you cancomevisitourwebsiteatwww.engvid.com,

andthereyoucandoourquiz.

Now,incase,youknow,maybeyoudidn'tunderstand thevideo,like,completelyormaybethere's

someconfusion,incaseyou're confused,watchthevideoagain.

Okay?

Youcangetalotfromwatching thesevideosmultipletimes.
