One syllable: meth.
/mɛθ/
Say it backMeth is a short, monosyllabic term primarily used as slang for the illegal drug methamphetamine. In broad use it appears in medical or legal contexts only as a shorthand reference rather than a formal term. The pronunciation is crisp and single-syllable, with a voiceless consonant onset and a final voiceless dental or alveolar stop, depending on regional variation.
"The lab was shut down after authorities found illicit meth producing equipment."
"She admitted she had used meth for years, which complicated her recovery."
"Methamphetamine is tightly regulated in most jurisdictions, and trafficking carries severe penalties."
The word is pronounced with a single syllable: /mɛθ/. Start with a bilabial–alveolar onset as in ‘meh’ and finish with a voiceless dental fricative [θ] as in ‘th’ in ‘think’. The vowel is a short mid-front vowel [e] (as in ‘bet’), followed immediately by the [θ] sound. In careful speech, the final [θ] should be crisp and not turned into [d] or swallowed. Stress is on the only syllable.
Common errors include substituting the final [θ] with a [t] or [d] (→ ‘meth’ becoming ‘meth’ with a stop), or delaying the [θ] so the word sounds like ‘meeth’ or ‘meathe.’ Some speakers may place the tongue too high or too far back, producing a lax or rounded vowel instead of clear [e]. The fix: keep the vowel short and crisp, bring the tongue to the teeth edge for [θ], and avoid adding a vowel after the final consonant in non-final positions.
Across accents, the initial [m] and vowel [e] stay stable, but the final [θ] can vary: in US and UK, it remains a dental fricative [θ], often shortened in rapid speech. Some UK speakers may voice the [θ] slightly or substitute with a [f] or an unvoiced [s] in certain dialects; in Australian English, [θ] is often preserved but with slightly stronger dental contact and shorter vowel duration before the fricative. Overall, rhotic vs non-rhotic patterns do not affect /mɛθ/ much since the word ends with a non-rhotic fricative.
The challenge lies in producing a clean, brief [e] vowel followed immediately by the fricative [θ], without inserting an intrusive vowel or turning it into [t] or [d]. The tongue must approach the upper teeth lightly to produce the voiceless [θ], while the lips stay relaxed. Rapid speech can turn the [e] into a schwa-like vowel, and some speakers may want to round the lips or tense the jaw. Focus on a short, crisp transition between vowel and fricative.
No, there is no silent letter in ‘meth’; the final sound is the voiced or voiceless dental fricative [θ]. Some speakers voice the final fricative in very casual speech, producing a weak [z]-like effect, but standard pronunciation keeps [θ]. The mouth position remains the tongue tip at the upper teeth edge with minimal lip rounding. If you hear an elongated or silent tail, it’s typically due to connected speech or misperceived voicing, not an actual silent letter.

Meth derives from methamphetamine, a synthetic stimulant first synthesized in the late 19th century by chemist Nagai Nagayoshi in Japan, who discovered it by reducing ephedrine. The term methamphetamine itself blends the prefix ’meth-’ from methyl and the word ‘amphetamine,’ pointing to its chemical structure as a methylated amphetamine. Early medical interest in methamphetamine as a nasal decongestant and bronchodilator appeared in the early 20th century, with mass production in the 1930s. Its legal medical usage expanded until concerns about dependency and abuse led to strict controls in many countries by the late 20th century. In contemporary usage, “meth” became the colloquial shorthand in English-speaking regions for illicit, highly potent forms of methamphetamine, particularly when sold as “crystal meth.” The word’s first recorded usage as slang in American English appeared in mid-20th century drug subcultures, and it has since become widely recognized in media and policy discussions. The evolution reflects a shift from a clinical term to a widely circulated street name, retaining a strong association with illegal activity, addiction, and the stimulant’s potent effects.
