silent letters - 3

the letter h is usually sounded in English, as in house, heart and home

BUT not always - in these words it remains silent:

ˈaʊə(r)   hour

ˈɑːnər    honour

ˈer        heir

ˈɒnɪst     honest

So, the correct indefinite article is an in front of these words:

He's an honest man

I've been waiting over half an hour

But remember, honesty is not always the best option

In the 'wh' combinations the h ususally remains silent, as in

what, where, when and why

But in the words who and whose the h is pronounced and the w is silent

huːz    whose
