Today I needed help:

“не мог/могла бы ты мне помочь с этим?”

“Could you help me with this”

“Voisitko auttaa minua tämän kanssa”

I took a look at the pronouns Russian Pronouns - Russian Grammar and got a bit frightened, but just a bit.

Words are:

1. мог/могл мочь - can, be able to - voida (voisitko is a conditional question)

2. помочь - to help (here in passive form) - auttaa

3. этим - this - tämän (Finnish uses accusative here, but Russian is dative 🤔)
