Accent-Specific Pronunciation Guide

How you approach this sound depends on your English accent. Find yours below for personalised coaching.

American English

Direct TransferDifficulty: 1/5

Direct transfer. Castilian Spanish z and c-before-e/i use the 'th' from 'think' — your voiceless dental fricative. Zapato = 'tha-pa-to'. Gracias = 'gra-thias'. Note: Latin American Spanish uses 's' instead — so this only applies if learning Castilian/European Spanish.

Bridge from: think, three, math (θ)

Common mistakes:

  • Using 's' when Castilian 'th' is intended (or vice versa)
  • This is a dialect choice, not an error — but be consistent

Drill sequence:

  1. think → zapato (tha-pa-to)
  2. three → gracias (gra-thias)

British English

Direct TransferDifficulty: 1/5

Direct transfer. Your 'th' = Castilian z.

Bridge from: think, three (θ)

Common mistakes:

  • None

Drill sequence:

  1. think → zapato

Australian / NZ English

Direct TransferDifficulty: 1/5

Direct transfer. Your 'th' in 'think' = Castilian z/ce/ci. Zapato = tha-pa-to.

Bridge from: think, three (θ)

Common mistakes:

  • Dialect consistency

Drill sequence:

  1. think → zapato

Irish English

Direct TransferDifficulty: 1/5

If you use the 'th' fricative in 'think', it's a direct transfer. Some Irish dialects use a dental stop instead — make sure it's a FRICATIVE (continuous airflow) for Castilian z.

Bridge from: think, three (θ / t̪)

Common mistakes:

  • Dental stop instead of fricative in some dialects

Drill sequence:

  1. think (fricative) → zapato

Scottish English

Common mistakes:

  • None

Drill sequence:

Indian English

Small AdjustmentDifficulty: 3/5

Indian English often uses a dental stop [t̪] for 'th' — 'think' becomes 'tink'. For Castilian Spanish z, you need the FRICATIVE version. Place your tongue between your teeth and blow air continuously — it should hiss softly. Don't let your tongue stop the air completely. This is the same challenge as the intervocalic d, but voiceless (no voice buzzing).

Bridge from: think → often 'tink' (t̪ (dental stop))

Common mistakes:

  • Using dental stop instead of fricative
  • Substituting 's' (acceptable for Latin American, but not Castilian)

Drill sequence:

  1. Tongue between teeth → blow air → soft hiss → /θ/
  2. think → fricative → zapato
  3. Practice: continuous air, no stop

South African English

Direct TransferDifficulty: 1/5

Direct transfer. Your 'th' in 'think' = Castilian z.

Bridge from: think, three (θ)

Common mistakes:

  • None

Drill sequence:

  1. think → zapato

Nigerian / W. African English

Small AdjustmentDifficulty: 3/5

Nigerian English typically uses [t] or [s] for 'th' — 'think' becomes 'tink' or 'sink'. For Castilian Spanish, you need the dental fricative: tongue between teeth, blow air continuously. Same technique as for the voiced version in intervocalic d, but without voice. Alternatively, if learning Latin American Spanish, just use 's' — which you already have.

Bridge from: think → often 'tink' (t / s)

Common mistakes:

  • Using stop instead of fricative
  • If learning Latin American Spanish, 's' is correct and this sound isn't needed

Drill sequence:

  1. Tongue between teeth → voiceless airflow → /θ/
  2. For LatAm: just use s → zapato = sapato
