Mission possible: Must, Might, Could

We use the modal verbs: Must, Might and Could when we want to express a possibility. So, imagine that Pepé de Ronda is an adrenaline junkie who is very keen on rock climbing and we want to know where he is.

So we ask: Where is Pepé de Ronda?

1. He MUST be rock climbing ( I am 100% sure)
2. He MIGHT be white water rafting. ( I am 75% sure)
3. He COULD be in the pub with Janette. ( 50% It’s a possible option)

Grammar Tip!  Please remember, if you use a modal verb, you have to use the bare infinitive in the following verb.  MODAL VERB+ BARE INFINITIVE (B.INF:without TO ) MUST BE, MIGHT BE, COULD BE
