20 Things Most of Us Think Are the Same—But Aren’t

You're probably saying these things interchangeably.

Poisonous and venomous

"Venomous" applies to animals that bite or sting, injecting toxins. Anything that's "poisonous" unloads toxins when you eat it, according to the Encyclopedia. So saying a snake is "poisonous" is almost always incorrect as the snake bite is what usually releases toxins. One exception is the garter snake which has a small or harmless bite but is toxic to eat, per the Encyclopedia.

Colleges and universities

"University" is an older word generally referring to institutions with both undergraduate and graduate or professional programs, per dictionary.com. "Colleges" emphasize undergraduate learning and might not have graduate degrees at all, although some still offer both programs. Another common difference between the two is that "colleges" tend to be smaller than "universities." The biggest difference between the two might be mostly cultural. Over time, "university" became more prestigious than "college" which is why some schools are changing their names. To make things even more confusing, some "universities" have "colleges" within them for different areas of undergraduate study. If your head hurts from thinking about this, prepare to have your mind blown by these things you probably never thought about—until just now.

Macaroons and macarons

One letter in spelling these sweet treats is a small difference between two almost completely different desserts. French "macarons" are meringue-based sandwich cookies with either ganache, jam, or buttercream filling. They are notoriously tricky to make, but macaroons aren't. "Macaroons" have shredded coconut as the main ingredient and are easier to make.

Robberies and burglaries

A "robbery" is some person-to-person interaction and theft with, "force, intimidation, or coercion," according to the Law Office of Nancy King. "Burglary," however, only requires intent to steal, it doesn't require actually stealing property or a personal interaction. Meanwhile, "theft" simply means you stole without interacting with anyone.

Climate and weather

"Weather" accounts for the day-to-day temperature, precipitation, and humidity in a specific area, according to the National Snow and Ice Data Center. "Climate," however, is a long-term average weather trend. So the weather might be 50 degrees, rainy, and humid for New York in April, but the climate might usually be warmer and wetter.

These are the hardest words to spell in the English language.

Turtles and tortoises

The Tortoise and the Hare could have another title if Aesop knew other animal distinctions. "Turtle" is an umbrella term for turtles, tortoises, and terrapins, according to National Geographic. "Tortoises" are turtles that strictly live on land and aren't made for water. Some turtles, however, are aquatic. An easy way to tell the difference between the two is to look at their feet as tortoise feet resemble elephant feet while turtles and specifically sea turtles have webbed feet or true flippers, per NatGeo.

Great Britain and the United Kingdom

Across the pond is either the United Kingdom or Great Britain, depending on who's talking. Although foreigners might mix up these words, they aren't interchangeable. According to the Encyclopedia, "Great Britain" is a geographic and political term referring to the island of Britain including Wales, Scotland, England, as well as some other small islands off the coast. The "United Kingdom" is a political term and independent country including all of Great Britain and Northern Ireland. So while Great Britain is part of the United Kingdom, the United Kingdom is not part of Great Britain.

Every Canadian should know these British words and phrases.

Jam and jelly

Everyone has a favourite jam and or jelly, but the sweet spreads aren't identical. "Jelly" is from the boiled sweetened fruit juice and pectin, a thickening agent. "Jam" has larger chunks of fruit as part of the fruit juice making jam thicker and often more flavourful.

The flu and colds

Colds and cases of the flu have lots of similarities, which is why some people confuse the two terms. They are both respiratory infections from viruses with some lousy symptoms. Some of the cold symptoms are a sore throat, runny nose, and maybe a nasal drip, too. "Flu" symptoms differ since the nose is sometimes congested, there's almost always fever, and extreme exhaustion. Unlike the flu, however, "colds" and cold symptoms don't last as long those of the flu and flu symptoms could develop or lead to serious complications.

Streets, roads, and avenues

These terms aren't just fun ways to change up the language of street names. "Roads" are typically throughways connecting two points, but "streets" are public roads with buildings on both sides, Mental Floss reports. So while "streets" are "roads," "roads" aren't "streets." Then there are "avenues" which run the opposite way of roads, either north-south or east-west, depending on where you live.

This is why Japan has blue traffic lights instead of green.

Whole wheat and whole grain foods

Products that are whole wheat are also whole grain, but not all whole grain products are whole wheat, as wheat is a type of grain. A food is "whole grain" if it uses the entire grain kernel including the outer bran shell and the germ, SELF reports.

Direct and non-stop flights

The important difference between "direct" and "non-stop" flights is that "non-stop" flights go from the first destination to the last. A "direct" flight, on the other hand, is an older term from days when flights made intermediate stops at airports along the path or route of the plane, sometimes for more fuel and sometimes without making passengers leave the plane, according to Travel + Leisure. These "direct" flights are far and few between nowadays thanks to more fuel-efficient jets.

Just try to guess how long the world's longest flight actually takes.

Motels and hotels

There are more differences between "hotels" and "motels" than their first letters. Both types of lodging have the same essential purpose of housing travellers, but plenty sets them apart, too. "Hotels," a term with French roots, offer lodging, meals, entertainment, and other services to travellers. "Motels" are a more recent American lodging option meant for one or two-night stops for road travellers. That's why hotels provide more amenities as guests stay longer. Even something as simple as a lobby is a bonus as motels typically offer access to rooms from the parking lot, per USA Today.

All-wheel and four-wheel drive

Yes, most cars have four wheels—but that doesn't mean "four-wheel drive" (4WD) and "all-wheel drive" (AWD) mean the same thing. Vehicles with 4WD are usually trucks or SUVs meant for off-road driving. These wheels work by sending power to all four wheels for traction as necessary. AWD vehicles have power going to all the wheels all the time. Although this still sounds quite similar, the main difference between "AWD" and "4WD" is that the car transitions into AWD without the help of the driver. Of course, there are also subcategories—there's part-time AWD, full-time AWD, part-time 4WD, and part-time 4WD. Here's what you need to know about them.

Yard sales and estate sales

Yard sales, garage sales, tag sales, and rummage sales are all pretty much identical. There is, however, a big difference between yard-type sales and an "estate sale." The homeowner runs a "yard sale," but outside paid people or companies run an "estate sale," according to Stacy Sporn, a real estate broker in New York.

Cement and concrete

Although people use "cement" and "concrete" interchangeably, they are different things. In fact, "cement" is the binding ingredient in "concrete," according to the Portland Cement Association. Concrete also has air, water, and a mix or combination of "aggregate" including sand, gravel, or crushed stone. The ingredients making up cement, however, include aluminum, iron, calcium, silicon, and other elements.

Retinol and retinoids

Skincare and beauty lovers should note that anti-aging ingredients retinol and retinoids aren't equal. "Retinoids" are a group of vitamin A derivatives, says board-certified dermatologist Edidiong Kaminska, MD, co-founder of Kaminsky Medical and Surgical Consulting Incorporated. These chemicals boost cell turnover, smoothing fine lines and evening skin tone. "Retinol" is a specific kind of retinoid that's not as powerful as a prescription retinoid.

Grocery stores and supermarkets

The products in grocery stores are also in supermarkets, but the opposite isn't necessarily true. The difference in products and store size are the main reasons "supermarkets" and "grocery stores" aren't the same thing. "Supermarkets" usually have a wider assortment of products going beyond food, but "grocery stores" stock a handful of household items at most, according to Jenna Coleman, a consumer behaviour analyst in the grocery sector and founder of Particular Pantry.

Here are some of the most intriguing foods from all corners of the globe.

Chocolate cake and devil's food cake

Although many people won't discriminate against delicious cakes, it is curious that chocolate and devil's food cakes are different. Many people think they're identical, but certain ingredients slightly change the taste and texture of each dessert. The general rule of thumb is that "devil's food cake" recipes usually include less butter and milk with more cocoa powder than traditional chocolate cake. Regular "chocolate cakes" rely more on butter and might call for other types of chocolate such as melted milk baking chocolates.

Baking soda and baking powder

A simple slip of the tongue or confusing baking powder and baking soda could make the difference between flat and fluffy baked goods. "Baking soda" is a crystalline weakly alkaline salt. "Baking powder" is a leavening agent usually containing baking soda as one of the base ingredients.
