I think the word future should start with the letter "P"
Phonetically it should sound like, "Peww Chur"
If you think about it (But not too much), it makes since.
Take for instance the tenses in which you conjugate verbs;
- Past
- Present
- Future
The word "Phone" starts with a P.
Why cant or shouldn't Future or now Phuture.
It is Law.
