संस्कृत / saṃskṛta > पठज्ञ > paṭhajña > One adept in teaching / study , scholar.
संस्कृत / saṃskṛta > चर्या > caryā > to care, to cure, 
संस्कृत / saṃskṛta > पद > pada > feet ,
संस्कृत / saṃskṛta > पितृ > pitṛ  > पिता > pitā  > Father, पैत्र > paitra  > patriarchal 
The above vocabulary (वाक् बलः ईय> वाक्बलरीय)  gives us clues how 

Pedicure , Pediatrics, (US : Pediatrics) Padre, Father, Pedagogue / Pedagog,

pedicure, pedophilia, might have originated from terms which have their meaning in संस्कृत / saṃskṛta well-derived and testified from the basic roots of  संस्कृत / saṃskṛta.

So we see how :

Pedagogue means 'Learned', or one associated with scholarship.

Father is the male parent as well as the one who helps in baptizing. 

On the other hand pedophilia means the condition of being sexually attracted towards children.

पैत्र > paitra  > patriarchal helps us understand the love of father for the child.

संस्कृत / saṃskṛta > पितृ > pitṛ > gives us 'Peter' (Saint?) or Peter (Simon) of Bible? Who knows?

A man of sane mind could not imagine that this could have a sexual-tone like Oedipus or Electra-Complex which we have known in the Development and Progress and new 'research' ' in Psychology of Date.

But the same Fatherly affection of a male-parent towards one's son / daughter has been distorted and took the form of pervert kind - 'pedophilia'.

In the same way from here we derive 'pedo' for 'child' and 'philia' for love / sexual-lust.

The Philosophy and Theosophy too hint at this.

And then we 'coin' a newer word  :

Pediatrics, (US : Pediatrics).
