"That tractor can lift tonnes with the right attachment."
Tonnes is pronounced /ˈtɒnz/ in UK and Commonwealth English and /ˈtɒnz/ or /ˈtɔnz/ in some US technical contexts; the core is the rhymes with 'tones' minus the long vowel in US. The stress is on the first syllable: TONNZ. Mouth: start with an open back round vowel for /ɒ/ (UK/AU), then a clear alveolar nasal /n/, and end with /z/. You can reference an audio model by saying 'tones' with a voiced z-ending.
Common mistakes include turning /ɒ/ into a more open or rounded vowel as in 'tan' in American speech, producing a voiceless /s/ instead of /z/ at the end, or adding an extra syllable. Correction: keep the vowel compact as /ɒ/ (UK/AU) or /ɑː/ in certain US technical readings, end with a voiced /z/ (not /s/), and avoid pronouncing an extra 'e' or pronouncing it like 'ton' followed by 's'. Practice with minimal pairs like tones/tonnes to feel the final z.
Across accents, primary variation is vowel quality in the first syllable: UK/AU tends toward /tɒnz/ with a short open /ɒ/ vowel, US sometimes leans to /tɑːnz/ or /tɔnz/ depending on regional rhoticity and vowel merging. The final /nz/ is often realized as a sustained voice with a clear z; Americans may have a slightly more nasal or shortened /ɔ/ or /ɑ/ depending on dialect. Overall the consonants stay the same: /t/ + /n/ + /z/.
The difficulty lies in the subtle vowel quality of /ɒ/ (UK/AU) or /ɑː/ (some US readings) and ensuring the final /z/ is voiced and not realized as /s/. Many speakers also misplace the stress or insert an extra vowel, turning it into 'to-ness' or 'ton-es.' Focus on keeping the first syllable compact, then finishing with a crisp, voiced /z/. Practicing with minimal pairs helps cement the final voiced consonant.
Tonnes has no silent letters; the letters T-O-N-N-E-S align to /t/ + /ɒ/ (or /ɑː/) + /n/ + /z/ with the final /z/ voiced. The 'e' is not silent in the British sense here; it's part of the plural form, if you consider orthography, but phonetically the ending is simply /nz/.

Tonnes comes from tonne, a metric unit of mass introduced in the 19th century along with the metric system. The term tonne derives from the French tonne, a corruption of the Old French ton, connected to the Large English ‘ton’ measure used in various contexts. The symbol t for tonne is standardized by the International System of Units (SI). The word tonne can be traced to late-medieval Latin tonna, likely from the Greek nton or the Celtic base for weight, evolving through English as a borrowed unit into Standard British and global scientific usage. The plural form tonnes appears in English when referencing multiple units, maintaining the same chemical/physical sense as a bulk quantity. First known uses appear in British scientific and commercial writing in the 19th century, aligning with the expansion of rail and global commerce that required standard mass units for trade and manufacturing.
