“乗せる” vs “乗っける”

Question

Good afternoon all,

I was wondering when someone gives someone a ride (bicycle, car, etc), what's the difference in nuance between using the verb "乗せる" and the verb "乗っける"?

For example, I was wondering what's the difference in nuance/usage between these two sentences:

1. でもその、自転車に乗せてくれた子に感謝しなくちゃね。

2. でもその、自転車に乗っけてくれた子に感謝しなくちゃね。

And these two sentences:

1. 入試の日に自転車に乗せてくれた子。

2. 入試の日に自転車に乗っけてくれた子。

Answer 1

乗っける is a colloquial and mascline (rough) way of saying 乗せる. In formal occasions, you should not use 乗っける.

Answer 2

乗っかる･乗っける are Kanto dialectal versions of 乗る･乗せる which have made it into the modern Tokyo dialect as colloquialisms.
