Should vs Could
 

Should and Could are two modal verbs in English that show difference between them when it comes to their meanings and usage. The modal verb should is normally used in the sense of ‘have to’. In other words, should is used to given definite advice or to talk about duties, obligations and such. The modal verb could is used in sentences that make a request or a suggestion. This is the main difference between the two modal verbs, namely, should and could. In the following article, you will be able to observe definitions and examples of the usage of the two words, should and could.
