Voiceless TH words

Voiceless TH uses the same tongue-to-teeth position as voiced TH but with no vocal cord vibration, just a stream of air. It shows up mainly in content words like think, thin and month. Common substitutions are s (sink for think) and t (tin for thin), so check that your tongue is actually between the teeth.
