Did you know that the simple TH sound in English actually has two distinct pronunciations? For many non-native speakers, this can be a bit overwhelming at first—but don't worry!

With the right tips and a little practice, you'll be pronouncing both versions like a pro.

One of these is the unvoiced TH /θ/, which you’ll find in words like "think" or "bath". This sound is created by gently placing the tip of your tongue between your teeth and letting the air flow through, without using your vocal cords.

It has a soft, breathy quality that sets it apart from other sounds.

Ready to master the unvoiced TH and make your English sound more fluent? Let’s get started!

The Unvoiced TH /θ/

The unvoiced TH /θ/ sound is produced by placing the tip of the tongue between the upper and lower front teeth and allowing air to flow through the narrow opening.

The sound is made without vibration of the vocal cords, resulting in a "breathy" or "hissing" quality. The sound is similar to the "s" sound in "think" or "bath" and does not require any significant effort from the throat.

Examples:

• think = θɪŋk

  I think so.

• thanks = θæŋks

  Thanks for coming.

• thousand = ˈθaʊzənd

  The painting costs a thousand dollars.

• through / threw = θru / θru

  She threw the ball through the window.

• nothing / ˈnʌ - θɪŋ

  There’s nothing here.

• birthday = ˈbɜrθ - ˌdeɪ

  My birthday is in March.

• health / healthy = hɛlθ / ˈhɛl - θi

  Healthy food contributes to good health.

• both = boʊθ

  Both are funny.

• tooth / teeth = tuθ / tiθ

  This tooth is a different color than my other teeth.

• month = mʌnθ

  We’re going to New York next month.

  north / south = nɔrθ / saʊθ

  Do I drive north or south?
