Auxilliary is similar to helper. It helps word or sentence to make a new pattern or meaning. Modal auxilliary is a group of auxilliary which modifies verb about ability/disability, possibility/impossibility, obligation/necessity, planning to do something, etc.
KEY: Put “BE” behind the modal auxilliary!
I can be angry (saya bisa marah)
She must be Irvan suhadi (dia pasti si irvan suhadi)
They will be here soon (mereka akan kesini segera)
You may be out (anda boleh keluar)
Put “not”behind the auxilliary to make a negative pattern!,
I can not be at home soon (saya tidak bisa pulang segera)
She must not be irwandi (dia pasti bukan irwandi)
They will not be on time (mereka tidak akan tepat waktu)
You may not be away from me (kau tidak boleh jauh dariku)
Can not = can’t /kant/
Will not = won’t /wount/
Must not = mustn’t /mazen/
May not = mayn’t /mei-yen/
(note: mayn’t is rarely used)
To make an interrogative pattern, place the auxilliary at the beginning of the sentence!
Will you be mine someday?
(maukah kau menjadi milikku suatu hari nanti?)
KEY: Put The Bare Infinitive behind the modal auxilliary! ( leave the “be”!)
Positive pattern : you can read the text.
Negative pattern : you can’t read the text.
Interrogative pattern : can you read the text?
