Dear all,

when working on pyigt, a Python package that handles interlinear-glossed
text in order to allow to represent it consistently in our machine- and
human-readable CLDF-format (https://cldf.clld.org) (draft here:
http://doi.org/10.17613/nppg-x393), we realized at some point that the
current practice of using symbols for the segmentation of words into
morphemes which ALSO have an inherent semantics that defines the
function of one of the elements that are separated with this very symbol
can be quite problematic, since it is often ambiguous, to which element
the semantics are attached.

The = vs. - symbols are a good example here, as a - b does not tell me
which is the affix, the a or the b. The plus, which we use as a standard
separator in our version of IGT in CLDF now is unproblematic, as it does
not provide different semantics to the elements it splits.

However, given these inconsistencies, it is now impossible to
consistently investigate larger collections of IGT that have been
published, since it is often not clear which element is what, unless the
relevant information is given in the gloss layer.

My recommendation is therefore to use one segmentation symbol only and
to mark the information of whether something is a clitic, a prefix, an
infix, etc., on the element itself, in the gloss. My argument is: if you
define the semantics in the glosses (and do this in a consistent way)
you don't need to think of whether it is a clitic, an affix, or
something else. So one can just get away with one symbol for the
segmentation, and still be much more explicit than we can often observe
in the current practice.

For those interested in the arguments, we had a discussion on github,
with Florian Matter, which we consider as resolved now:
