What role is the い playing in "している"?


The sentence

> トニーはいい声をしている。

apparently translates to

> Tony's voice is nice.

**Question:** The verb "している", according to jpdb.io, is the て continuous
conjugation of する. But when I look up the て continuous conjugation elsewhere,
I see it written as "してる" (without the い). So what is the い doing here in
"している"?




してる is a colloquial spelling/pronunciation of している. The continuous forms of
verbs are created by taking the ―て form and adding your desired conjugation of
いる. In casual spoken Japanese the い is sometimes dropped in the continuous
form of verbs because it's easier to pronounce. The い is not "playing a role,"
rather it is being dropped in very casual speech.
