Considering words such as slow and sleep…..
I thought, right from when I was first learning, that it would be easier to write s-l using a right-S rather than the left-S which we use. It is much more “facile” (to use an expression commonly used in describing Gregg writing). I quite understood at the time that it was far more “distinct” to use the left-S.
I see that the right-S could be perceived as producing a form which could morph into something else, but now, knowing other places where similar possible uncertainties could arise when reading, I wonder, again: why? Frequent use of this joining would have made it just as distinguishable as anything else.
I’d never dream of doing such a thing, but the question remains.
