A lot of people seem to think Chlo-/Clo- is an “ugly” sound, but
Chloe is one of today’s most popular names. I think it’s all based on associations.
Chloe brings to mind the perfume, young celebrities, and so on, so it’s “usable.”
Clovis and
Chloris bring no associations to mind (except a vague datedness), so the “weird sound” becomes more of an issue.
Life—the greatest adventure for which one could ever ask. 人生は最高な冒険ですね!
