There some Auxiliary Modals in English we have to know when we study about sentence. However, in this occasion we will only study Modal “COULD”. In this case we will study Function and Pattern of Auxiliary Modal COULD so that we will be familiar to this auxiliary. (also learn : Function and Pattern of Auxiliary Modal CAN)
Before studying about the function and its examples, it is better we study the pattern or the form of sentence using Modal COULD. As other auxiliary modals, the pattern of Modal COULD is able be shown as below:
She could play guitar.
They can stay here.
( – ) Subject + Could + not + infinitive (verb 1) + Complement
She could not play guitar.
They could not stay here.
( ? ) Could + Subject + infinitive (verb 1) + Complement
Could she play guitar?
Could they stay here?
Below is the explanation about Function and Example of Auxiliary Modal COULD
The Function of Modal COULD
There are some functions of Auxiliary Modal “COULD” that is able to be studied, they are:
A. As the past form of “can”
He said he couldn’t come so early.
I couldn’t remember who he was.
When I was young, I could run in a long time.
Could you open the window, please?
Could you turn up the heat?
Could you remind him to call?
C. To show possibility, however, “MAY” and “MIGHT” are stronger
She could be with her parents.
He could still win, but it’s not very likely.

We hope the material about Function and Pattern of Auxiliary Modal COULD above can improve our understanding about English, especially about auxiliary modal COULD.
