I'm confused about how to pronounce a word such as 一組. Are Japanese or Chinese numbers used when using 組 as a counter, and if the former how does it change phonetically?
For example, jisho.org lists both いちくみ and ひとくみ for 一組. My IME accepts both of those as 一組 and also takes いちぐみ, いっくみ, and いっぐみ. Which if any of these is the correct or at least most common pronunciation?
