Hiragana - Long vowel e (ei or ee)


I am wondering about the long vowel _e_ , and whether it is _-ee_ or _-ei_.
Let's use _hē_ as an example, is _hē_ written as へい or へえ?




Long vowel E is usually written using い, so, へい is correct. There are some
exceptions where it is written with え such as ねえさん、but these are exceptions to
the rule, and don't change pronunciation.

There are also a few other ways the vowel can be written as extended:
sometimes the ー mark will be used just as in katakana, and sometimes a smaller
え is used, for example when ending a sentence with ねぇ. However, again, these
are exceptions, so it's best to assume that the vowel is extended with い.
