hi guys i'm arnelle and today we're

looking at

because as since and for

[Music]

okay if we look at these four words

because is the most common

and the most used yes

as since and for can be used in many

different ways

but today we're specifically focusing on

them

as synonyms of because

so if you see the sentence i've lived

here since 2010

that's correct but that's not what we're

looking at today

i work as a teacher fantastic but that's

not what we're looking at

today today we're specifically focusing

on

result and reason result

and reason result okay i have my results

and reason i have a headache

because i didn't sleep well i

take the bus to work because i don't

have a car

because it introduces our reason why we

do something

why do i have a headache because i

didn't sleep well

actually before i continue we need to

look at something very quickly

because versus because of

say meaning different grammar because

plus subject and verb because of plus

noun or pronoun

i stayed home because it was raining out

i stayed home because of the weather

i have my subject and my verb i have my

noun

we canceled the class because not enough

students enrolled

we cancelled the class because of low

student numbers

subject plus verb and there i have my

noun

so this grammatical difference is

important for you to remember

so keep these rules in mind okay back to

these two examples

let's look at these same sentences with

as and since

i have a terrible headache because i

didn't sleep well

as i didn't sleep well since i didn't

sleep well

i take the bus to work because i don't

have a car

as i don't have a car since i don't have

a car

perfectly correct but let's get a little

bit

more specific because

focus is more on the reason as and since

focus more on the results

i don't talk to amy anymore because she

lied to me

everyone is really happy because

tomorrow is a day off

off meaning no work and no school

here because she lied to me

tomorrow is a day off these are my

reasons and they are more important

the roads ahead are currently closed as

or since they are being repaired

i'm not sure what to do as since

lauren hasn't responded to my message so

yes

as in since they do introduce the reason

but we are focusing more on the result

rather than the reason because

the reason is already clear to the

speaker and the listener

for example okay let's start the meeting

as everyone is here we can see everyone

is here

if you're on a walk

we should head back since it's starting

to rain

we can see we can feel it's starting to

rain

so far we've learned because focuses on

the reason

as or since focus on the result often

because the reason is already clear

because it's more common as or since are

less common

more formal four i haven't done four yet

we'll get to that let's keep going

in this lesson i've used because as and

since in the middle of my sentence

here are a few examples

she lied to me i don't talk to her

anymore

since laura hasn't responded to my

message i'm not sure what to do

as i don't have a car i take the bus to

work

perfectly correct you can put the reason

clause

at the beginning but do you notice

anything

anything kind of small let's get closer

a little closer

even closer

oh you have a happy little comma waving

and saying hi

okay if you use because as or since at

the beginning of your sentence

make sure you have that comma to

separate the two clauses

using because at the start of your

sentence gives you reason

even more importance for example

because our bodies are made up of 70

water it's important to stay hydrated

this is more emphatic than saying it's

important to stay hydrated

because our bodies are made up of 70

water

and because because is so common

we often just say cuz i can't check my

messages

because i left my phone at home why did

you put an

empty milk carton back in the fridge

because i was busy you can see

the because claws can stand alone

because i was busy because i wanted to

because i had extra time this is

perfectly fine in spoken english

this would not work with as or since

why did you put an empty milk carton

back in the fridge

as i was busy since i was busy

that doesn't work so what

about four four can also mean because

right when four is used as a conjunction

it also means

because abigail lowered her head

and wept for she knew her tom was dead

okay you might be thinking huh that's a

really weird example

when we use for to mean because we often

see it in

literature literary context and very

formal situations

you can also see i'm using the verb weep

wheat meaning cry weep meaning cry

for meaning because is not something you

would see

day to day at all it's something you

might see

in poems or novels it would be very

unnatural if you emailed your boss and

said

good morning maggie i won't be able to

attend the meeting today

before i have a terrible headache just

use

because okay i hope you can use

because as since four a bit more

confidently now
