/ˈfaɪɚz/
Say it backFires is the third-person singular present tense and plural noun form of fire, meaning to discharge a weapon, to ignite or to dismiss from employment. It also refers to multiple occurrences of combustion or, in forestry, wildfires. In grammar, it can function as both a verb (he fires) and a noun (the fires raged).
"The firefighter battles the fires that swept through the hillside."
"She files a report as the engine fires up."
"Several companies face layoffs as they are fired and the workers lose their jobs."
In US/UK English, fires is pronounced with the diphthong /aɪ/ followed by a voiced /ɹ/ plus /z/: /ˈfaɪərz/ in careful speech. The stress is on the first syllable: FAIRS-like with a lighter /ɹ/ sound before the final z. In rapid speech, the /ɪə/ sequence can be realized as a quicker glide, but the core sounds remain /ˈfaɪərz/. Mouth position: start with a high-front tongue for /f/, then rise to /aɪ/ with a slight diphthongization, finish with a voiced alveolar /z/.
Common errors: mispronouncing the /aɪ/ as a short /ɪ/ (fi-ers instead of /faɪərz/), or turning the /ər/ into a schwa-vowel sequence (fa-ers). Another error is pronouncing /z/ without voice (silencing the final z). Correction: keep a clear /aɪ/ glide, pronounce the /ər/ as an r-colored schwa /ər/ or /ɜr/ depending on accent, and voice the final /z/. Practice the two-pointer: /faɪ/ + /ər/ + /z/.
In US English, /ˈfaɪərz/ with rhotic /r/; in many UK accents, /ˈfaɪəz/ or /ˈfaɪəz/ with non-rhotic /r/ and a shorter /ə/; Australian often /ˈfaɪəz/ with light rhotic involvement but consistent /z/. Vowel length and the rhotic quality of /r/ vary: US holds /ɹ/ clearly, UK may gloss /r/ in non-rhotic contexts, and AU tends to a mid-front vowel with less centralized /ə/. Listen for whether the /r/ segment is pronounced before the final /z/.
The difficulty centers on the diphthong /aɪ/ and the /ər/ sequence leading into a voiced /z/. For non-native speakers, the challenge is maintaining the glide from /aɪ/ to /ə/ or /ər/ while keeping the final /z/ voiced and audible. The cluster /ɪər/ or /ɪə/ can blur in rapid speech. Additionally, the S-end /z/ voice can be devoiced in rapid contexts. Focus on keeping the first syllable strong and the final voiced sibilant clear.
Is there any subtle distinction between the noun fires (flames) and the verb fires (shoots or dismisses) in pronunciation? No. The pronunciation remains the same /ˈfaɪərz/ across senses; the difference is solely in stress in context if you treat the noun as a heavier first syllable in certain compound phrases (e.g., ‘the fires department’ keeps primary stress on fires as a unit). The same IPA applies in both noun and verb forms.

The word fires derives from the Old English fȳr, which itself comes from the Proto-Germanic *fuiran- and is cognate with Dutch vuur, German Feuer, and Gothic faihu. The term originally referred to the act or state of burning and to the physical flames themselves. In Middle English, fire shifted to include both the substance and the act of setting something alight, and by the 13th century, the verb sense began to appear in texts meaning to discharge a weapon or to dismiss from service. The plural form fires began to appear in the sense “flames” or “incidents of burning” and also in the idiom “to set on fire” in a figurative sense. The verb sense “to shoot” or “to dismiss from employment” matured in the 16th–17th centuries as firearms and military jargon influenced everyday English. The noun-use as an event or set of flames became common in news and literature through the 18th–19th centuries, with the adjective-fire in compounds like fire-related. Today, fires is used in both countable senses (two fires) and as a verb form (he fires).
