Use of connecting vowels after stems ending in the same vowel: a proposal to emend Appendix 9 of the International Code of Nomenclature of Prokaryotes.

The International Code of Nomenclature of Prokaryotes (ICNP) provides guidance on the formation of names from compound words. This includes recommendations on the use of connecting vowels, which are meant to make names easier to pronounce. However, deployment of a connecting vowel when the preceding word element ends in the same vowel can make a name harder to spell or say, bringing us into conflict with the recommendations that we should avoid names that are disagreeable and difficult to pronounce. Given that there are many precedents where connecting vowels are not used in this context, particularly in names formed from the term 'alkali', I hereby propose an emendation to the ICNP to drop the connecting vowel when the preceding word element ends in the same vowel.
