You've probably seen it on a plaque, heard it in a graduation speech, or maybe you just caught a rerun of the British detective show Endeavour and wondered why they didn't just call it "Effort." It’s a heavy word. It feels like it weighs more than its synonyms. When someone asks what does endeavour mean, they usually aren't looking for a simple dictionary snippet. They want to know the vibe. They want to know why we use this specific, slightly old-fashioned term instead of just saying "trying hard."
Honestly, the word is about the struggle.
Technically, to endeavour is to attempt something with a serious amount of effort. It’s a verb and a noun. But in the real world, it’s about the gap between wanting something and actually getting it. It’s the sweat. It’s the 3:00 AM wake-up calls. It’s that feeling of pushing against a door that might be locked, but you’re going to keep leaning on it anyway.
The Gritty Roots of the Word
Language is weird. The word comes from the Middle English endevour, which basically meant "to do one's duty." It’s linked to the French phrase en devoir, meaning "in duty." Back in the day, if you were endeavouring, you weren't just "giving it a go." You were fulfilling an obligation. You were doing what had to be done.
Think about that for a second.
Nowadays, we treat it more like a choice. We "endeavour to be better people." We "embark on a new business endeavour." But that DNA of duty still lingers under the surface. It implies that the task at hand isn't just a hobby. It’s a mission.
Why the British Spelling Matters
You’ll notice I’m using the "u"—endeavour. That’s the British English spelling. In the United States, it’s usually simplified to endeavor. Both are right. It just depends on which side of the Atlantic you’re standing on. However, because the word feels so formal and prestigious, even some American brands keep the "u" to make it sound more sophisticated or historical. It’s a bit of a marketing trick, really.
What Does Endeavour Mean in Different Contexts?
If you're looking for a dry definition, the Merriam-Webster dictionary says it is "to attempt by exertion of effort." But that’s boring. It doesn't capture the spirit of Captain James Cook’s ship, the HMS Endeavour.
When Cook set sail in 1768, he wasn't just "trying" to find a continent. He was heading into the absolute unknown. That is the essence of the word. It’s not just effort; it’s effort directed toward a significant, often risky, goal.
In Science and Space
NASA loves this word. They named a Space Shuttle Endeavour. Why? Because space travel isn't a casual trip to the grocery store. It’s the peak of human capability and risk. When NASA uses the term, they are signaling that the mission requires every ounce of brilliance and bravery available.
It's about the collective.

A scientific endeavour usually involves hundreds of people. Think about the Large Hadron Collider or the James Webb Space Telescope. These aren't just "projects." They are endeavours because they take decades, cost billions, and push the boundaries of what we actually know about the universe. If it can be done in a weekend, it's not an endeavour. It's a task.
In Business and Entrepreneurship
You'll hear CEOs use this word a lot in annual reports. "We are committed to this new endeavour in renewable energy."
Translation: "This is going to be expensive, it might fail, but we're going all in."
In business, an endeavour is a venture. It’s a startup. It’s a pivot. It carries the weight of capital and reputation. If a friend tells you they’re starting a "small business," they’re being humble. If they say they’re starting a "new endeavour," they’re probably looking for investors or feeling particularly ambitious that day.
The Psychological Weight of Trying
There’s a reason we don't use this word for small things. You don't "endeavour" to brush your teeth. You don't "endeavour" to watch a movie.
Psychologically, using this word changes how you view your work. It frames your struggle as something noble. Dr. Carol Dweck, the Stanford psychologist who pioneered the "growth mindset" concept, doesn't use the word "endeavour" specifically in her core research, but the philosophy fits perfectly. To endeavour is to embrace the "not yet." It is the active pursuit of mastery.
It’s about the process, not just the result.
Most people focus on the finish line. But the word itself is rooted in the doing. If you're endeavouring, you are currently in the thick of it. You are in the mud. You are working.
Misconceptions: What It Isn't
People mix this up with "intend" all the time.
If I say, "I intend to go to the gym," I’m just talking. There is no action involved. I might be sitting on the couch eating chips while I say it.

If I say, "I am endeavouring to get fit," it implies I’ve already bought the shoes, I’m tracking my macros, and I’m probably sore right now. Intent is a thought. Endeavour is a verb. It requires calories.
Another misconception is that an endeavour has to be successful to count.
Wrong.
Some of the greatest endeavours in history were total disasters. Look at the various expeditions to find the Northwest Passage. Many of those were heroic endeavours that ended in tragedy. The word describes the attempt, not the trophy. It’s about the "exertion of effort," as the dictionary says, regardless of whether that effort pays off in the end.
The Cultural Impact of the Word
We see this word pop up in literature and media because it sounds "important."
Take the TV show Endeavour. It’s a prequel to Inspector Morse. The protagonist’s first name is Endeavour Morse. It’s a weird name, right? His parents were Quakers, and they liked the idea of naming a child after a virtue or a noble pursuit. Throughout the series, the name acts as a constant reminder of his character: he is a man who is defined by his work, his intellectual struggle, and his persistence in the face of a messy, often depressing world.
It tells the audience everything they need to know about him without saying a word. He isn't a guy who takes the easy path.
Using it in Your Own Life
Should you start using this word in your daily conversations?
Maybe.
If you use it to describe making a sandwich, you’re going to sound like a jerk. But if you’re talking about a long-term goal—learning a language, raising a child, writing a book—it’s actually a very grounding word. It acknowledges that what you’re doing is hard. It gives you permission to be tired.

Nuance: Endeavour vs. Strive vs. Attempt
Let's break these down because they aren't exactly the same.
Attempt is neutral. You can attempt to jump over a puddle. It’s quick. It’s done.
Strive is more emotional. It feels like you’re reaching upward. You strive for excellence. It’s aspirational and a bit poetic.
Endeavour is more industrial. It feels like a machine or a large ship. It’s methodical. It’s persistent. It’s not just a "reach"; it’s a sustained push.
If you’re trying to choose the right word for a speech or a letter, think about the scale. "Strive" is for the heart. "Endeavour" is for the hands.
Real-World Examples of Modern Endeavours
- The Human Genome Project: This was a massive international endeavour. It wasn't just one guy in a lab. It was thousands of scientists working for 13 years to map our DNA.
- Climate Change Mitigation: This is arguably the biggest collective endeavour in human history. It’s messy, it’s controversial, and it requires a level of global cooperation we've never really seen before.
- Parenting: Honestly, if anything fits the definition of a "sustained effort toward a significant goal," it's raising a human being. It's a 20-year (at least) endeavour.
How to Apply This Knowledge
Knowing the definition is one thing. Living it is another. If you want to take the concept of an endeavour and actually use it to improve your life, you have to change how you look at "failure."
Since an endeavour is about the effort and the "duty" to try, failing doesn't mean the endeavour was a waste of time. It just means that specific attempt is over.
If you are currently working on something that feels heavy—a career change, a difficult relationship, a creative project—stop calling it a "task." Call it your current endeavour. That shift in language does something to your brain. It makes the struggle feel like a choice you’ve made rather than a burden you’re forced to carry.
Actionable Steps for Your Next Big Project
- Define the Scope: Is this a one-off task or a true endeavour? If it's going to take more than a month and requires significant personal growth, treat it with the respect an endeavour deserves.
- Acknowledge the "Duty": Find the "why." Why is this your duty? Who are you doing it for? Connecting effort to a sense of purpose is the fastest way to prevent burnout.
- Track the Effort, Not Just the Goal: In an endeavour, the work is the point. Keep a log of what you did today, even if you didn't reach the final destination.
- Accept the Friction: The word implies difficulty. If it was easy, we wouldn't call it an endeavour. When things get hard, remind yourself: "This is exactly what an endeavour feels like."
The next time someone asks you what you're up to, and you're in the middle of something big, something life-changing, something that keeps you up at night, don't just say you're "busy." Tell them you're engaged in a new endeavour. It sounds better. It feels better. And it’s a whole lot more honest about the work you’re putting in.
