/ˈfɔɹzɪz/
Say it backForces is the plural form of force, meaning units of energy or power that cause movement, influence, or physical strength. It can refer to groups wielding power, or to physical forces in science (e.g., gravity, friction). In everyday use, it also appears in phrases like “military forces” or “acting under force.” The word is typically stressed on the first syllable and functions as a noun in most contexts.
"The civil rights forces helped organize the march."
"The engine’s forces were not enough to overcome the hill."
"She joined the security forces to assist in crowd control."
Pronounce as FOR-siz with primary stress on the first syllable. IPA: US /ˈfɔːr.sɪz/; UK /ˈfɔː.sɪz/; AU /ˈfɔː.sɪz/. Start with a rounded open-mid back vowel /ɔː/ like “thought” in non-rhotic varieties, then a light, quick /r/ if you’re American; in non-rhotic accents the /r/ is not pronounced before a vowel. End with /sɪz/ (or /z/ depending on voice context). Keep the final /z/ voicing consistent unless followed by a consonant in connected speech. Practice with “FOR-siz” in a steady, clipped tempo to land the first syllable clearly before the quick, z-voiced second syllable.
Common errors include pronouncing it as FORS-iz with an /s/ instead of the /z/ in the second syllable, or weakening the first syllable to a schwa (/fə-siz/). Also some speakers misplace stress as for-ces, or add an extra syllable like /ˈfɔːr.siːz/. To correct: emphasize the first syllable with a clear /ɔː/ vowel and keep the final /z/voicing. Keep the /r/ rhotic in US practice, or omit it in non-rhotic accents. End with a short, but distinct /z/ rather than a voiceless /s/.
In US English you’ll hear /ˈfɔːr.sɪz/ with an explicit rhotic /r/. UK English tends toward /ˈfɔː.sɪz/ with non-rhoticity in many dialects, so the /r/ isn’t pronounced unless followed by a vowel. Australian English often has a clipped, broad /ɔː/ and a clear /z/ ending, with some vowel shift making /ɔː/ slightly broader and the r-coloring reduced. In all cases, the final /z/ remains voiced; ensure you maintain a sharp, voiced endpoint rather than a hissy /s/.
The difficulty centers on the transition from the long vowel /ɔː/ to the quick /r/ (in US varieties) and then to the voiced final consonant /z/. For non-rhotic accents, the /r/ may be silent, which shifts perception of the word’s rhythm. The final /z/ can cause voice-onset-time mismatches if you’re not keeping vocal fold vibration, leading many learners to use /s/ instead. Paying attention to the shift from the stressed vowel to the sonorant /r/ (or its absence) and then maintaining voicing in the end is key.
Is the /ɪ/ in forces a true /ɪ/ or a reduced schwa in fast speech? In careful speech, the second syllable is /ɪz/ with a light /ɪ/ depending on the speaker; in fast connected speech, it can reduce toward /əz/ or even elide slightly in rapid phrases like “forces acting.” Focus on keeping /ɪ/ distinct from /iː/ and ensuring the final /z/ remains voiced. IPA guidance: /ˈfɔːr.sɪz/ (US), with careful measurement of the /ɪ/ duration.

Forces comes from the Latin fortis meaning strong, via Old French force and Anglo-French force. The term first appeared in Middle English as forte or force, reflecting the idea of power or strength. In physics and mechanics, the word evolved to describe influential quantities that cause changes in motion, beginning with early scientific texts in the 17th century when notions of push and pull were formalized. The plural form forces emerged as a general term for multiple agents of influence, whether physical, social, or military, paralleling the pluralization of “power” to indicate different sources. By the 18th and 19th centuries, “forces” became common in military discourse (e.g., assembling armed forces) and in science, where one discusses gravitational forces, electromagnetic forces, and contact forces. Today, the plural is used across domains to denote several influences acting on a system or group, while the singular force is discussed in physics standards. First known use as an abstract noun from Old French, with attestations in English as early as the 13th century, the word solidified its broad range of meaning through legal, military, and scientific texts in the modern era.
