Definitely! But what are “modal verbs” exactly? Are they different from “Auxiliary verbs like Do-Does-Did- etcetera”? 

Modal verbs are different from auxiliary verbs and from the rest of verbs  because they carry a special meaning or intention, added  to main verbs. They are very easy to use because they always keep the same format for all subjects (I might, she might, they might); that is, they do not take up a conjugation,  and they are always followed  by a verb in base form (I might see him, she might go, they might arrive). In general, MIGHT or its negative form MIGHT NOT,  (you do not use a contracted form in the negative),  is a modal auxiliary that is used to express  an unlikely or uncertain possibility .

Here are some examples: 

• Melissa might be late for the meeting tomorrow. She hasn´t been feeling well lately and she needs to go to the doctor in the early morning.
• You should take your coat with you, Dad. It looks like it might snow this evening.

• My boss might not go to the Monterrey Conference next week. He isn´t sure yet.
• There might be some pizza left over in the fridge, Mike.  I´m not too sure.
• We might  visit  our grandparents in Acapulco  this weekend, but it depends on the weather.
• Jackie might  come to her sister´s wedding next month, but she isn´t sure yet. It depends on a loan she wants to get.     
• We might go to the Book Fair on Sunday, Monique, if you want to come.

That´s right. You can also use MAY/ MAY NOT instead of “might” to express  a weak possibility or certainty. Here are some examples.

• My colleagues and I may have a meeting tomorrow afternoon, if we finish our project on time.

• Sorry, I may not be able to go  to your party in Cabos  next Saturday. I have an important exam coming up soon and I need to study.
