English is messy. Honestly, it’s a disaster of a language held together by duct tape and historical accidents. If you’ve ever sat staring at a blinking cursor wondering if it’s "collectable" or "collectible," you aren’t alone. You’re just a victim of a linguistic tug-of-war that’s been going on for about a thousand years. Words ending with able are everywhere, and they are deceptively difficult to master because the rules aren't actually rules—they're more like loose suggestions.
Some people think suffix usage is just for spelling bees. It isn't. It's about how we perceive the world. When you call a phone "fixable," you’re making a claim about its engineering. When you call a person "likable," you're making a social judgment. These words describe potential. They describe what could be.
The Latin Trap and Why Spelling Is So Weird
Most of our frustration comes from the fact that English is a scavenger. We have two main suffixes that do the exact same job: -able and -ible. They both basically mean "capable of" or "worthy of."
So why do we have both? Because Latin.
The -able suffix generally comes from the Latin -abilis. However, it also became the "living" suffix in English. This means whenever we invent a new word today—like "tweetable" or "zoomable"—we almost always tack on -able. It’s the default. The -ible ending is like a fossil. It usually shows up in words that came directly from Latin or through French, like credible (from credere) or audible (from audire).
If the base word is a complete English word on its own, you’re usually safe with -able. Take "depend." It’s a word. Add the suffix: dependable. Easy. Now look at "incredible." Is "incred" a word? No. So it gets the -ible.
But English loves to make you look stupid.
Think about "collectible." By the logic I just gave you, "collect" is a word, so it should be "collectable," right? Well, both are actually accepted, but "collectible" is more common in professional contexts. It’s annoying. You’ve got to just memorize the exceptions or use a spellchecker that hasn't given up on life.
How Words Ending With Able Change Your Business
In the world of commerce, "able" is a power move.
Marketing experts spend millions trying to find the right adjective to make a product feel essential. In the 1920s, the "washable" silk movement changed how people bought clothes. Before that, if you got a silk dress dirty, you were basically out of luck or headed for a very expensive specialist. By labeling something washable, brands removed the "risk" of the purchase.
Modern tech does the same thing with "scalable."
If you are a founder pitching to a VC in Silicon Valley, you aren't just building a company; you're building a scalable enterprise. This word is the holy grail. It means the system can handle growth without breaking. It’s the difference between a local bakery and a global franchise.
The Psychology of Capability
Words like reliable and accountable aren't just descriptors. They are contracts.
When a brand says their truck is "reliable," they are setting a baseline for your expectations. If it breaks down in a week, the word "reliable" becomes a weapon you use against them in a Google review. Words ending with able carry the weight of a promise.

Dropping the E: The Silent Killer of Confidence
Here is where most writers trip up. What do you do with a word like "value"?
If you want to say something has value, do you write "valueable" or "valuable"? You drop the 'e'. Usually. But then you look at "sizeable" vs "sizable." Both are technically okay depending on if you're in London or New York.
- Advise becomes advisable.
- Desire becomes desirable.
- Believe becomes believable.
Generally, if the word ends in a silent 'e', you toss it in the trash before adding the suffix. But wait! If the word ends in a soft 'c' or 'g'—like "change" or "notice"—you must keep the 'e'.
Changeable. Noticeable. If you wrote "noticable," it would look like it rhymes with "icicle." The 'e' stays there to protect the sound of the consonant. It's a tiny bodyguard for your pronunciation.
The Social Weight of Being Likable
Let’s get away from grammar for a second and talk about people. We use words ending with able to categorize each other constantly.
"Likable" is a weird one.
In politics, the "likability" factor is often cited as the reason candidates win or lose. But what does it actually mean? Is it about being nice? Or is it about being relatable? Research from the Journal of Personality and Social Psychology suggests that likability is a mix of perceived competence and warmth.
Then there’s "accountable."
This is the favorite word of middle managers everywhere. "We need to hold people accountable." It sounds professional, but it’s often used as a euphemism for "we need someone to blame when this goes south." Language is a tool for shifting responsibility.
Why Some Words Disappear
Languages evolve. Some words that were common 200 years ago are now basically extinct.
Have you ever used the word "amiable"? It sounds like something out of a Jane Austen novel. We still use it, but "friendly" has mostly taken its place in casual chat. Or "serviceable." It used to be a compliment. Now, if you tell your partner their cooking is "serviceable," you’re probably sleeping on the couch. It’s a word that has been demoted from "high quality" to "just barely good enough."

We also see "affordability" trending during every economic downturn.
It’s a word that shifts based on who is saying it. To a billionaire, a $100,000 car is affordable. To a teacher, it’s a fantasy. The suffix -able makes the word subjective. It depends entirely on the "ability" of the subject.
How to Get This Right Every Time
You don't need a PhD in linguistics. You just need a few mental filters.
First, look at the root. If the root is a "stand-alone" verb, use -able. Think of words like readable, drinkable, fixable, and breakable. These are the workhorses of the English language.
Second, check for the "Soft C/G" rule. If you see a 'c' or a 'g' at the end of the root, keep that 'e' in place.
Third, recognize when you're being manipulated. When a company describes a fee as "non-refundable," they are using a suffix to close a door on you. When a politician calls a situation "unavoidable," they are using a suffix to dodge blame.
The beauty of these words is their flexibility. You can turn almost any verb into an adjective just by sticking this suffix on the end. It's a "Lego piece" for sentences.

Actionable Steps for Better Writing
- Check your roots. If the word feels "Latin-y" and the base doesn't stand alone (like visible or terrible), it's probably an 'i'. If it's a common English verb, use 'a'.
- Audit your adjectives. Are you using "able" words to be vague? Instead of saying a report is "readable," try saying it's "clear" or "concise."
- Watch the 'e'. Remember the "bodyguard" rule. Keep the 'e' for manageable and traceable. Drop it for adorable and usable.
- Context matters. "Reasonable" in a legal contract means something very specific compared to "reasonable" in a conversation about the price of eggs. Know your audience.
Language isn't a static thing. It's a living, breathing mess that reflects how we think. Using words ending with able correctly won't just make you a better speller; it will make you a more precise thinker. You’ll start to see the difference between what is "possible" and what is "probable." And in a world full of noise, that kind of clarity is actually pretty valuable.
