Yorkshire batsman Root first came across Stokes in an Under-12s tournament when the all-rounder was representing Cumbria.
Stokes may have had to move to nearby Durham in order to pursue a first-class cricket career, but Root reckons many of the fiery all-rounder's enduring traits as a player were on show from an early age.
And knowing him as well as he does, Root was happy to nominate Stokes as his vice-captain after he himself accepted the top job last weekend following the resignation as Test skipper of Alastair Cook.
Recalling his first impression of Stokes, 26-year-old Root, not bothering to suppress a grin, said: "He was a little podgy medium-pacer back then.

He's obviously a slightly different player right now," added Root, speaking at his Headingley home ground.
"But he was always in your face, letting you know he was there -- and that was great to play against.
Root has had a close-up view of Stokes's skill on the Test stage, be it his blistering double century against South Africa in Cape Town last year or his five-wicket haul in England's 2015 Ashes-clinching victory at Trent Bridge, a match destined to be remembered for Stuart Broad's remarkable eight for 15 on the first day.
"He's very 'in your face', and sometimes you need that up-front brashness," said Root of Stokes.
"Then, the way he played in South Africa was just incredible -- and he is that sort of player that with the odd moment in the field can really change a game, turn it on its head."
Cook said one reason why he was able to lead England in a record 59 Tests was to avoid social media, thereby remaining ignorant of the more extreme criticism that came his way.
"It's something I've grown up with in international sport, so I'm used to it," Root explained. "With Cooky, it came along half way through his career.
"With the new age we're in now, where social media is a big part of communicating and getting things out there, it's something you've just got to adapt to and accept ... It's always going to be there.
"It's a great opportunity to get your messages across as well.
