I need help my Mom.
What they meant to say was:
I need to help my Mom.
So today let's look at the difference between need & need to.
Need
This means that you require something. In Japanese, いる (要る).
I need more free time.
Do you need a ride?
Do you need any help?
Need to
This is a bit different, need to means that you must do something.
My Mom said I need to help my brother with his homework.
What do you need to do today?
I need to go to work.
Another more casual way of saying need to is have to:
I have to go to work today.
I have to catch my train = I need to catch my train.
Have a great weekend,
