Trap 1 of 22 · French speakers
TH is not S or Z: think, this, three
Le TH : think, this, three — pas sink, zis, tree

What French speakers do
You replace TH with the nearest French sound: S or T for think (sink, tink), Z or D for this (zis, dis).
The American rule
Put the tip of the tongue between the teeth and push air out. Without voice for think (/θ/), with voice for this (/ð/).
This is the trap French speakers are best known for, and the one that comes up most: the, this, that, there, they, think, thank you — they are in almost every sentence.
English has two TH sounds, and French has neither:
- /θ/, without voice — think, three, thank, month. Tongue tip lightly between the teeth, blow air like a soft s.
- /ð/, with voice — the, this, mother, together. Same tongue position, but switch the voice on: you should feel a buzz on the tongue.
Practise in a mirror: if you can't see the tip of your tongue, it isn't a TH. It feels exaggerated at first; at normal speed the tongue barely peeks out.
