A - Azalea - the 13th which offers reward for those brave enough to go for the green in two. But be wary, the water in front of the green has caught many players out.
B - Birdie opportunities - the aforementioned azalea is your best chance, but whoever is wearing the green jacket on Sunday night will need to take advantage of the 15th, the 8th, and the 2nd.
C - Chokers - Rory McIlory threw away a four stroke lead going into the final day in 2011. But it wasn't the worst, with Greg Norman taking a six shot lead into the Sunday in 1996, before losing by five to Nick Faldo.
D - Dinner - the previous year's winner plans the 'Champions Dinner.' Patrick Reed served up rib-eye steak on Tuesday.
E - Eagles - there were 25 of them last year, some are more spectacular than others.
F - Flowers - many of the holes are named after flowers, and trees.
G - Green jacket - the jacket all players want to be wearing on Sunday night.
H - Holes in one - they don't happen too often, with just 29 recorded at the Masters since the first in 1934. Managing one on the 12th is the rarest feat, with the last of three coming way back in 1988.
I - Irish in Augusta - RTÉ Sport's Conor Neville has you covered.
J - Jones, Bobby - the lawyer, and best amateur golfer of the 1920s, who played a key role in getting the course built in the early 1930s.
K - Keiser, Herman - the American became the king of Augusta in 1946, after having joined the US Navy during the second World War. It was his only major win. Ian Woosman's only major also came at Augusta in 1991.
L - Langer, Bernard - the German was the most recent of his two green jackets in 1993.
M - Magnolia Lane - lined by 61 magnolia trees on each side, the spectacular driveway to the clubhouse at Augusta runs to just over 300 metres.
N - Nicklaus, Jack - the tournament's most successful player, with six Masters to his name. The first came in 1963, while the last came in 1986, after a gap off 11 years to his fifth title.
O - Oak tree - the Galway tent of Augusta, under which the who's who of golf meet during Masters week.
P - Patrick Reed - the tournament's defending champion.
Q - Qualify- there are 19 ways to qualify for the tournament, from being the defending champion, to being the Olympic golf champion, which entitles you to an invite in the year immediately after the games.
R - Rory McIlroy - the county Down golfer is going for the grand slam of golf, having already won the other three major titles. He's using some new psychological techniques, as he told our Greg Allen.
S - Shane Lowry - the Offaly man is the other Irish player in the field this week. His only other appearance at Augusta came in 2016, when he came home in a tie for 39th.
T - Tiger Woods - the American became the youngest win at 21 in 1997, and went on to win another three green jackets thereafter. It's 14 years since his last win. Woods is amongst the favourites this year.
U - Under par - the aim is to go under par, but on three occasions, an over par has been enough to claim a green jacket. The most recent winner to do this was Zach Johnson in 2007 (+ 1).
V - Viktor Hovland - one of six amateurs at the tournament this year, he recently said that if he played his game, he could beat Jordan Spieth and Tiger Woods - what he lacks in experience, he makes up for in self belief!
W - White Dogwood (11th) - the most difficult hole, statistically, in 2018. Players managed just 13 birdies over the four days, but there were 20 double bogeys.
X - Extra holes. The tournament has gone to a playoff 16 times, most recently in 2013 when Adam Scott defeated Angel Cabrera.
Y - Yellow Jasmine - the 8th is a par 5, but with the second shot usually being played blind, birdies are the order of the day here.
Z - Zoeller, Fuzzy - the American won on his debut in 1979, and collected his second major title at the 1984 US Open.
