Cusp

Nice word cusp. Can't think why it isn't used more. It's not as though it doesn't have many uses.

A cusp is a pointed end where two points meet. This could be part of a tooth (pre molars are bicuspid as they have two pointy bits) or an architectural or biological feature. Eg the top of a gothic arch, a leap point or part of the valves in our hearts.

If a mathmatical curve reverses abruptly that change is marked by a cusp and cusp is also the name given to the pointed ends of a new moon.

Cusp can also denote a transition of some kind. Those who's birth sign is on or near the end of a period are said to be on the cusp. Eg if your birthday is on 20th March you're on the cusp of Pisces and Aries (what that means I haven't a clue!) Teenagers are sometimes considered on the cusp of adulthood (as are middle-aged writers!)

Hi Patsy - cusp is a good word ... I hadn't twigged about the pre-molar aspect .. bicuspid ... and yes the cusp always occurs for those born in the 2nd third of the month ... heaven help the teenagers and their cusp! Cheers Hilary

I've always liked the word cusp, but it took me until maths 1 at university to see a visual and understand where the figurative meaning of cusp comes from.

I think teenagers are just completely over the edge...

Frances Garrood said...

A. Interesting word, and always preceded by "on the", isn't it. Nothing is ever over or under or beside the cusp. I wonder why...

Author R. Mac Wheeler said...

...'he was mad, so he cusp.'

Vikki said...

I love that word too!

Patsy said...

Thanks, Rosemary. I've forgotten which cathedral this is. Glasgow maybe?

Patsy said...

Such a little word, so many uses, Hilary.

Patsy said...

I confess to not understanding the mathmatical use of the word, Misha.

Patsy said...

You could well be right, Alex.

Patsy said...

I hadn't thought about that, Frances but yes, you're right.

Patsy said...

Um ... maybe if he had a lisp?

Patsy said...

It is nice, Vikki.

The writer was on the cusp of fame and fortune ...

Great word! It reminds me of my mother - a woman who was fascinated by astrology. I learned this word from her when I was a little girl.

I'll drink a couple cusp of coffee to that. (Tee-hee-hee.) Nice pic! I'm on the cusp of finishing my novel.

Christine Rains said...

You know, it is a nice word to say. It slithers off the tongue so neatly. :)

Patsy said...

Teetering perilously, no doubt, Linda!

Patsy said...

A good word to teach you, Susan.

Patsy said...

I'm on the cusp of getting some work done, Oscar.

Patsy said...

It does, Christine.
