What is an unambiguous single word for a five-pointed star without enclosure?

I am looking for a single word that describes this thing (1):

but not this thing (2):

The obvious choice here would be pentagram, but in colloquial use, that word unfortunately refers to both (1) and (2), as well as a number of variants of (2) that have other enclosures surrounding the 5-pointed star. (In mathematical use, "pentagram" uniquely refers to (1) and not (2), but I am not writing for a mathematical audience, so that's still a no-go.) It also has connotations I would like to avoid (devil worship, goat sacrifice, etc.).

If all else fails, I can just call (1) a "five-pointed star", but that gets to be a bit of a mouthful.

• Funny, I just ran across a passage in a Harry Dresden novel that relied on exactly this precise distinction between a pentagram and a pentacle. And I had to read it like three times to get it straight, even though I was aware of the difference. So this is an apt question, I think. Mar 26, 2014 at 9:16
• It's a satan worshipping star-thingy. You are out of luck :) Mar 26, 2014 at 9:56
• @mplungjan no, it's the first star I learned to draw :-)

• You could put dashes in "rotationally-symmetric-stellate-pentagon": en.wikipedia.org/wiki/Equilateral_pentagon#Stellated I'm pretty sure there's only one such object, and it's the one you supplied. Mar 26, 2014 at 12:46
• Note that in some situtaions "Sheriff's Star" can help here. Mar 27, 2014 at 8:24

To reiterate what you described, in strict usage the following apply:

This is a pentagram – a type of five-pointed star

This is a pentacle – a pentagram circumscribed by a circle:

This is a five-pointed star that is not a pentagram:

Yes, as you described, strict usage is not always the case, and when you say pentagram it evokes pentacle in the minds of many people. However, I am convinced that there is no single word that is both common and unambiguously understood to mean the first case. I am assuming that since you consider five-pointed star "a bit of a mouthful" that you mean to repeat this term at least a few times in whatever you're writing. If I were in your place, I would use the term pentagram (since after all, it is correct in formal usage), and use a picture to show the reader exactly what you mean. If you are writing in a medium where you cannot use pictures, I would spend a sentence to describe it as a five-pointed star drawn with five straight strokes.

According to Wikipedia, it is a Pentagram.

Wikipedia points out that Pentacles are magical objects and

despite the sound of the word, often had no connotation of "five" in the old magical texts, but were, rather, magical talismans inscribed with any symbol or character.

• Interesting note about pentacles! Mar 26, 2014 at 23:37

Doczi in 'The Power of Limits' p 6, viewable here, distinguishes between a pentagon, a pentagram and a pentagonal star (this last (highlighted in bold) refers to your (1) above). Unfortunately it's 2 words, not 1.

• -> "pentastar" to coin something (you'll probably find a better neologism but I doubt you'll find a single word that's unambiguous without defining it) Mar 26, 2014 at 17:10

If you must avoid pentagram then consider:

• pentacle
• pentalpha
• pentangle

Or in some cases you could just say star.

Isn't the occult/demonic pentagram upside-down — rotated 180 degrees?

Knowing more would help. What is the context? Who is the audience? Why are you seeking this one word label?

• 'Isn't the occult/demonic pentagram upside-down — rotated 180 degrees?' -- No, it is only rotated 72 degrees. Mar 26, 2014 at 16:00
• @Lighthart ITYM 36. Mar 26, 2014 at 16:45
• @Lighthart Well, there's an infinite number of solutions in the form of: 36 + 72c for any integer c. Mar 26, 2014 at 17:32

At the risk of being banished from the site for eternity for language bending, what about `pentapoint`?

Disclaimer: `pentapoint` is not an English word.

pentastar or pentalpha would be correct answers.

• Do you have some source that says these are English words? Mar 26, 2014 at 12:52
• penta is not an English word. It comes from greek and widely used in English. And you anyway know that "star" is an English word.
