I see that 'Daktylo' is Greek for 'finger', from reading these comments. Sadly, I don't know one iota of Greek!

Did you know that our fingerprints are formed by us touching the walls of our mother’s womb when she is pregnant with us?
This has got to be my favourite ever fact, and can’t believe I only learnt that this year. You’d think that a fact like that would be common knowledge!

A typewriter in Turkish is 'daktilo', so I guessed the answer must be related to fingers.
