may and might

(1) There is no such thing as the 'present infinitive'. It is the bare infinitive, 'tell', as we use with all the modals-- can tell, will tell, should tell, etc.


(2) Not the same. The continuous form is a present possible activity. He might be waiting at the moment.

The simple (not 'present') infinitive is in the unspecified future. He might wait there tomorrow or next year.

Hope this helps, Navi.

But, it's here in my book , might + present infinitive

Sounds like a Japanese textbook, Navi...

Seriously, I just googled for it, and it is indeed in some books-- looks like an attempt to attach classic Greek verb form classification to English.

Is this what your book has?--

Present infinitive: 'go'
Past infinitive: 'went'
Past participle: 'gone'?

Often called 'simple present (dictionary form)', 'simple past', 'past participle ('-ed' form)'. I suppose there are other names.

Anyway, it doesn't change my assessment of your original inquiry.

Eureka !

we use the infinitive without be when we use might / may :

You may be right. ( not you may to be right ).

He might tell his wife. ( not he might to tell his wife ).

Thanks Mister .. :wink:

Nice pairing of avatars too, eh?

Good night.
