My new favorite word: Interpunct

As I'm working on building a curriculum for vocabulary, most especially around morpheme analysis and word sums by WordWorksKingston, I'm thinking way too hard about the little things.  I would love some feedback from any SLA experts, ESOL teachers, or general classroom teachers out there who can shed some light on my question:

Do the hyphens used to end or begin a prefix or suffix confuse your students?

Thinking about this like an eight-year-old, which is not much different than thinking about it like the adult I am, learning this in depth for the first time, I see the hypen as a subtraction symbol. How is an eight-year-old without a significant number of words to communicate their confusion supposed to know inherently that they are meant to add that suffix to the stem, not subtract it, when this is the first time they have seen morpheme analysis.

Unless someone stops me, I have half a mind to use an interpunct (·) in lieu of the hyphen.  Instead of de-, students will see de·.  It makes sense to me that we should use the same symbol used to separate syllables to separate affixes from stems, as they are also the place where will break up the word between syllables. 

De·tail·ing

De·:“to pull away”, “away, off"

·Tail·: coming from a French word meaning "to cut"

·Ing: progressive/continuous

All I had to do was search "etymology detail" and Google did the work for me

When you are detailing something, you are considering something cut away from the rest of the original, larger picture.  As Gus said in My Big Fat Greek Wedding, "So der you go."

Again, perhaps I'm over-thinking this, but removing the hyphens prevents eight-year-old ELL-me from thinking about subtraction and allows me to make the connection to syllabification.

What do you think? I would love some insight on this. Tell me if I've "discovered" something that was A) never really a problem or B) is already a topic of discussion in SLA research.
