What do a light bulb, door knob, and coffee mug have in common?  Yes, they’re all things that you would find at your workplace.  But I wasn’t referring to the items themselves.  Instead, I wanted you to think about their pronunciation.

Each of these words is called a noun compound, and they have a special pronunciation in American English.

Whenever you put two nouns together, like light + bulb, you make a compound, and the first word is pronounced stronger than the second: LIGHT bulb, DOOR knob, COFFEE mug.

You can tell the difference in the stress because if you change the first word to an adjective, then the second word gets stressed.  Listen to these examples: a broken BULB, a shiny KNOB, an empty POT.  Did you hear the difference in stress?

The rule is pretty simple, but students of English don’t always say these combinations right, which can confuse their American friends.  For example, can you distinguish a PIG barn from a big BARN?

Noun compounds are all around us: ink pen, book case, table leg, camera operator, a haircut...  Once you get going, you’ll notice them everywhere.
