Is 'Pokenose' correct? Irregular verbs and some correct pronunciations

Good morning KIB students.
I'm glad to see more people in class today.

Most of you had cut class to go see Facebook reality show. It came in different episodes. Very interesting I must say.

You all went there to savour the juiciness of the 'meet and greet' tale.

Anyway,  thank God you are here now. Let me give you the scoop. Let's get down to brass tacks.

Let's look at these three irregular verbs.

Cast
Broadcast
Forecast.

I am yet to hear anyone use the tenses of these verbs correctly.
Even media personalities usually make these grave mistakes you are about to read.

1. He casted them in to a lake of fire
2. It need to be casted away.
3. They have finally broadcasted the news to everyone
4. When is it going to broadcasted?
5.  It's has been forecasted that it will rain tonight.
6  meteorologist have forecasted that there would be a massive flood  tomorrow.

Only 5 and 6 are correct here.

Cast and broadcast remain the same always. Their past tense and past participle are still the same.

1. He cast then into a lake of fire
2. It needs to be cast away
3.when is it going to be broadcast?
4. They have broadcast the news to everyone.

These aforementioned sentences are correct.

Another question is 'is pokenose correct?

Well there is no word like pokenose at all, but there is an idiom know as 'poke ones nose into something'.

Don't say he is pokenosing into my affairs, rather say "he pokes his nose into  my affairs"

Pokenosing and  pokenosed are  Un-English.

Finally,   
Tomb has a silent /b/. It's pronounced /two-m/ like /tu:m/

The class with King Ifey is done and dusted. Share your notes with people okay?

King Ifey loves you.

*walks out of the class.  Peeps through the window.

I thought you should still be reminded that 'savour' and 'saver' are homophones.

Toodles.
