Today Robin finished the cover for "Through a Wine Glass Darkly," a collection of fifteen of my short stories and (5) 100 word drabbles. All of the stories except one were published in anthologies, print or online, in 2016-2017. Consider this a best of collection.  When the publisher approves everything, usually 72 hours, I'll post the cover, the link, and the price. By multiple copies.

On a grammatical matter, today I'll look at three similar words commonly used as prefixes, inner, intra, and inter. Proper usage isn't difficult, although incorrect usage abounds.

First word is "inner." This is easy. "Inner is a word all by itself. Don't add it to another word. Inneroffice is not a word. Don't do that. Inner office is proper grammar, but still don't use the words that way. Inner  means "father inside," although colloquially it's used to mean "inside." If you mean inside, say inside.

That brings us to the other five letter prefixes, intra and inter. These are not words. Well, technically, inter is a word, but it isn't pronounced like you think and it means to put a corpse in a grave. Nice.

As a prefix, inter means between, among, mutual, shared, carried on, or reciprocal. For example, interracial - among the races, intergalactic - between the galaxies,  and intercourse (shame on you, it means to talk together.

As a prefix,intra means within, during, or between layers.

If you don't know which one to use, here are two tests. First, don't use inner as a prefix. That was easy.

Second, substitute the word, inside. For example, do you want to say interdenominational or intradenominational.  Interdenominational means there are several denominations that share something. Intradenominational means something inside a single denomination. Got it. Go forth and trust your inner judgement. I mean interjudgement, no that's not right. Must be intrajudgement.

Hell, just be careful out there.
