The modal verbs are:

can could
may might
shall should
will would

We use modal verbs to show if we believe something is certain, probable or possible (or not). We also use modals to do things like talking about ability, asking permission making requests and offers, and so on.



Hello, I have a question please. I am a little bit confused about the wording of my sentence written in my report (in the action items section): "The investigator to correct the entry" meaning that the investigator has/needs to correct the entry. Is my first sentence correct? is it possible to remove "has/needs" in the sentence when we want to use "have to" need to"? I'm not quite sure about my wording even if I'm sure I have heard some phrases like this... Thank you for your help.

Hello Kouldz
I've come across this in business documents such as action lists and minutes of meetings, so yes it is appropriate for the action items section of your report and your wording is correct.
I hope this helps
All the best
