The “th” sound in English can vary significantly between British English and Irish English, depending on the region and accent. The two main “th” sounds are: 1. The unvoiced /θ/ as in “think.” 2. The voiced /ð/ as in “this.” British English (RP): • “Th” sound is articulated properly: • The tongue is placed between the teeth for both /θ/ and /ð/ sounds. • Example: • “Think” → /θɪŋk/ • “This” → /ðɪs/ • This is standard in Received Pronunciation (RP) and many southern British accents.
