This one rewards a little close attention—looking at each of the words and figuring out their different meanings or sounds.

I’ve always loved heteronyms and how we can have a single word spelt the same and yet pronounced quite differently — like read — and how that clearly makes English a crazy language to learn. And, as you probably do too, I pretty much woke up at night thinking how you could sort words into groups of the same or different spelling and the same or different sounds and begin to make sense of these curious groups of words like homographs, homophones and heteronyms.

Words with different spellings and different sounds generally just mean different words.

There are nice buckets of other words too like contranyms — words that can be their own opposite.

I did think a third axis of the same or different meaning may give the complete picture but would probably just serve to confuse things.

Some Greek: homo—same, hetero—different, graph—written, phone—sound

This sketchplanation was edited to remove contranym from words with different sounds and spelling as they’re the same word. D’oh

Homonyms, homographs, homophones, heteronyms… 

It turns out when our body gets excited about something, we can’t reliably tell what caused the excitement.

In David McRaney’s brilliant article, he explains how we routinely misattribute physiological arousal and how the most common target of misattribution is other people. It’s part of why doing challenging or exciting activities with your partner can help strengthen your relationship, and why roller coasters and scary movies can make great first dates — when we reflect on the time, we often assume that it was the person we were with that helped get our heart racing rather than the excitement of the activity.

The misattribution of arousal

I’d never really thought this through before, but just a tiny lip makes a massive difference. Should be a standard feature on pretty much every saucepan.

How a lip stops drips.
