Grammar Rule in 30 Seconds
Use ~mono nara to express a deep, often impossible, desire or a hypothetical situation that is contrary to reality.
- Attach to the dictionary form of a verb: {行く|いく}ものなら
- Use for situations that are unlikely or impossible to happen.
- Often implies a sense of regret or longing for a different outcome.
Overview
~たら (-tara) or ~ば (-ba) handle realistic 'if-then' scenarios. The grammar pattern 〜ものなら (-mono nara), however, operates in a different, more emotional dimension. It's used to discuss a hypothetical situation that the speaker perceives as impossible, highly improbable, or fantastical.〜ものなら is about ability. It attaches to a verb's Potential Form to frame a condition around the *capacity* to perform an action, rather than the action itself. This structure serves two primary, powerful functions: expressing a deep, often regretful wish for an unattainable outcome, or issuing a challenge that dares someone to attempt something the speaker believes they cannot do.〜ものなら is a gateway to expressing nuanced feelings of longing, frustration, and defiance that are central to natural, emotive Japanese.How This Grammar Works
〜ものなら is derived directly from its three components: a potential verb, the nominalizer もの (mono), and the conditional particle なら (nara). Understanding each part's contribution is key to grasping the grammar's deep-seated nuance.- 1[Verb in Potential Form]: The Core of 'Ability'. The structure is built upon the Potential Form (
〜れる/〜られる). This is the most critical element. It shifts the entire focus from an event happening (e.g.,雨が降る- it rains) to someone's *ability* to make it happen (e.g.,戻れる- can return). By starting with 'can X,' you are already in the realm of capability and feasibility, not just facts. - 2
もの(mono): Nominalizing the Possibility. Here,ものfunctions as a nominalizer, but it does more than just turn the verb phrase into a noun. It reifies the potential action, turning 'being able to do X' into a tangible concept or a 'state of affairs.' So,戻れるもの(modoreru mono) is not just 'a thing that can return,' but 'the very possibility/matter of being able to return.' This is a subtle but crucial distinction that sets the stage for a hypothetical discussion. - 3
なら(nara): The Conditional Frame. The particleならtakes a topic or concept (in this case, theものphrase) and uses it to set a conditional boundary. Its meaning is close to, 'if *that's* the case...' or 'speaking of which...' When you combine it,[V-Potential + もの] + なら, the full meaning emerges: 'If the possibility of being able to [Verb] were the case...' This phrasing inherently signals that the speaker is considering a scenario contrary-to-fact or reality. The condition isn't a simple 'if,' but a commentary on the (un)likelihood of the 'possibility' itself.
人生をやり直せるものなら (jinsei o yarinaoseru mono nara), the literal breakdown is: 'If the matter of being able to redo one's life were a real possibility (which we both know it isn't)...' This underlying acknowledgment of impossibility is what imbues the pattern with its characteristic tone of longing or challenge.
Formation Pattern
[Verb (Potential Form)] + ものなら / もんなら
ものなら (mono nara) directly to the end.
ものなら is often contracted to もんなら (monnara).
ものなら | Casual Form |
買う (kau) | 買える (kaeru) | 買えるものなら (kaeru mono nara) | 買えるもんなら |
godan) | 話す (hanasu) | 話せる (hanaseru) | 話せるものなら (hanaseru mono nara) | 話せるもんなら |
待つ (matsu) | 待てる (materu) | 待てるものなら (materu mono nara) | 待てるもんなら |

来る (kuru) | 来られる (korareru) | 来られるものなら (korareru mono nara) | 来られるもんなら |
なる (naru), and then conjugating なる to its potential form, なれる (nareru).
i-Adjective: 若い (wakai) -> 若くなる (wakaku naru) -> 若くなれる (wakaku nareru) -> 若くなれるものなら` (If I could become young)
na-Adjective: 静か (shizuka) -> 静かになる (shizuka ni naru) -> 静かになれる (shizuka ni nareru) -> 静かになれるものなら (If I could become quiet)
When To Use It
〜ものなら in specific situations where you need to highlight the gap between a desired ability and the reality of its impossibility.- 1To Express Impossible Wishes and Deep Regret:
〜たい (-tai).あの頃に戻れるものなら、何でもする。(Ano koro ni modoreru mono nara, nandemo suru.) - 'If I *could* go back to those days, I'd do anything.'病気の母と代われるものなら、代わってあげたい。(Byōki no haha to kawareru mono nara, kawatte agetai.) - 'If I *could* trade places with my sick mother, I would want to.'
- 1To Issue a Challenge or Dare ('If You Can, Then Try'):
〜てみろ) or suggestion (〜てみてください).そんなことが一人でできるものなら、やってみろ。(Sonna koto ga hitori de dekiru mono nara, yatte miro.) - 'If you *can* do something like that by yourself, then go ahead and try!' (Implies: I doubt you can.)この問題が解けるもんなら、解いてみろよ。(Kono mondai ga tokeru monnara, toite miro yo.) - 'If you *can* solve this problem, then solve it!' (A casual dare among friends.)
- 1To Hypothesize About Fantastical Abilities:
空を飛べるものなら、まずはどこへ行きたい？(Sora o toberu mono nara, mazu wa doko e ikitai?) - 'If you *could* fly, where would you want to go first?'過去に行けるものなら、恐竜を見てみたい。(Kako ni ikeru mono nara, kyōryū o mite mitai.) - 'If I *could* go to the past, I'd want to see the dinosaurs.'
When Not To Use It
〜ものなら can make your Japanese sound unnatural or unintentionally aggressive. Avoid it in the following contexts.- 1For Realistic, Achievable Conditions:
〜たら, 〜ば, 〜なら, or 〜と.- Incorrect: ❌
明日、時間が作れるものなら、映画を見に行こう。(Ashita, jikan ga tsukureru mono nara, eiga o mi ni ikō.) - Correct: ✅
明日、時間が作れたら、映画を見に行こう。(Ashita, jikan ga tsukuretara, eiga o mi ni ikō.) - 'If I can make time tomorrow, let's go see a movie.'
- 1In Formal or Objective Writing:
〜ものなら makes it inappropriate for academic papers, business reports, or news articles. Its purpose is to convey personal feeling, not objective facts.- 1When the Condition is a State, Not a Potential Action:
だ/です), other patterns like 〜（だ）としたら are correct.- Incorrect: ❌
私が社長であるものなら、給料を上げる。(Watashi ga shachō de aru mono nara...) - Correct: ✅
私が社長だとしたら、給料を上げる。(Watashi ga shachō da to shitara, kyūryō o ageru.) - 'If I were the president, I would raise salaries.'
Common Mistakes
[V-Dictionary Form] + ものなら TrapV-Potential + ものなら | If I *could* do X... (longing) | 休めるものなら、休みたい。 (If I *could* take a break, I'd want to.) |V-Dictionary + ものなら | If you *dare* to do X... (warning) | 休むものなら、覚えておけ。 (If you *dare* to take a break, you'll regret it.) |V-るものなら pattern is often followed by a negative outcome, while V-れるものなら is followed by a desire.〜たい or 〜たらいい（のにな） are far more natural. Use 〜ものなら only when the barrier feels genuinely insurmountable.- (At a restaurant):
ケーキが食べたい。(I want to eat cake.) - Natural. - (On a diet, staring at cake):
ケーキが食べられるものなら、今すぐにでも食べたい。(If I *could* eat cake, I'd eat it right this second.) - Expresses the frustration of not being able to.
Real Conversations
You'll encounter 〜ものなら (and especially 〜もんなら) frequently in informal, emotional contexts where people are being candid about their feelings.
- On Social Media (commenting on a throwback photo):
うわー、懐かしい！この時代に戻れるもんなら戻りたいなー。
(Uwā, natsukashii! Kono jidai ni modoreru monnara modoritai nā.) - 'Whoa, nostalgic! If I could go back to this era, I'd love to.'
- In Manga/Anime (a rival's challenge):
俺に勝てるもんなら、かかってこい！
(Ore ni kateru monnara, kakatte koi!) - 'If you think you can beat me, bring it on!'
- Venting to a Friend via Text:
もう無理。仕事辞められるもんなら、明日にでも辞めたい。
(Mō muri. Shigoto yamerareru monnara, ashita ni demo yametai.) - 'I can't take it anymore. If I could quit my job, I'd quit as soon as tomorrow.'
- Standalone wistful expression:
A: 社長に昇進おめでとう！ (Shachō ni shōshin omedetō!) - 'Congrats on the promotion to president!'
B: ありがとう。でも、できるものなら、普通の社員に戻りたいよ… (Arigatō. Demo, dekiru mono nara, futsū no shain ni modoritai yo...) - 'Thanks. But if I could, I'd want to go back to being a regular employee...'

- できるものなら、＿＿＿＿＿＿＿＿！ (e.g., ...やってみろ！ - Go ahead and try!)
Scenario Application: How would you say the following in Japanese?

- Answer: あの車、買えるものなら買いたいなあ。 (Ano kuruma, kaeru mono nara kaitai nā.)
- 'Your friend boasts they can eat 10 bowls of ramen. Challenge them.'

Error Correction: Find and fix the mistake in the sentence below.
- 明日のテストを受けるものなら、いい点を取りたい。 (Ashita no tesuto o ukeru mono nara, ii ten o toritai.)
- Correction: The verb should be potential. 明日のテストを受けられるものなら... (ukerareru mono nara). However, this is still unnatural as taking a test is usually possible. A better sentence would be simply: 明日のテスト、いい点を取りたい。 The ~ものなら pattern is inappropriate here.
Quick FAQ
〜ものなら and 〜たらいいのに?Think scale and focus. 〜たらいいのに expresses a general wish that a situation were different ('I wish it would stop raining'). 〜ものなら focuses specifically on the speaker's lack of ability to change a situation, and is often used for larger, life-altering, or fantastical impossibilities ('If only I could go back in time').
〜ものなら always negative or pessimistic?The *condition* is framed as negative (impossible), but the *result* the speaker wants is usually positive (a desire to do something good, like help someone). The overall feeling is one of melancholy or wistfulness because the positive outcome is blocked by the impossible condition.
〜ものなら? Can I use it with my boss?〜ものなら itself is stylistically neutral, but its emotional nature makes it best for conversations with people you know well. Using it with a boss about a personal wish (e.g., wanting to go home) might sound a bit too emotionally candid. The contracted 〜もんなら is strictly informal and should be avoided in professional settings.
〜ものだ / 〜ものではない?No, they are completely different. 〜ものだ is used to express general truths, social norms, or strong convictions ('Students *are supposed to* study'). The fact that both use the nominalizer もの is a coincidence in function; their grammatical roles and meanings do not overlap.
