A language in which numbers and symbols are put together to look like letters. Some people create their own 1337 letters and it makes them look more 1337 by fellow 1337-speakers. Here is an alphabet of 1337 letters I know and have created:

A: 4 or l\ or ^ or @ or /\ or /-\
B. l3 or 8 or ß or ]3 or l:
C: ( or < or © or ¢
D: l) or l> or ])
E:3 or £
F: l= or # or ƒ
G:6 or 9
H: # or l-l or (-) or !-! or }-{ or }{ or l+l or )+( or !+! or }+{
L: 1 or ! or ]
J: _l or _/
K: l< or l( or l{ or l<=
L: l_ or ! or 1
M: l\/l or /\/\ or l\l\ or ^^
N: l/l or /\/
O: 0 or () or <> or * or ø or Ó or °
P: l* or l> or |D or l^ or l+
Q:& or (\) or ¶
R: l2 or ®
S: 5 or $ or §
T:+ or 7
U: l_l or /_/

Words that use other characters. Tend to become very annoying. Here's a list of what each letter is substituted by, usually.
A = 4 or @
B = l3
C = (
D = cl, or |)
E = 3
F = Nothing for F, but you can use ones from different types of languages. Such as ㅋ, which is from Korean alphabet(hangul)
G = 9
H = |-|
I = !, or 1
J = nothing for J
K = l<,
L = |_
M = lVl
N = lV
O = 0
P = not that i know of
Q = still nothing that i know of
R = i got nothing
S = 5
T = +, or 7
U = |_|
V = \/
W = \/\/
X = i got notin
Y = >-
Z = still notin

1337 is the language of hackers and newbies across the internet. Also, the words in 1337 are usually short(ie "are" becomes "r") and intentionally spelt wrong(ie "the" becomes "teh", this is most common with e switching places and o's becoming p's)

the mostly complete translation chart(exluding unicode characters, ie ©):
A=4 /-\ @ ^ /\
B=8 ]3 ]8 |3 |8
C=( {
D=) } |) |} |> >
E=3
F*=# |=
G=6 9 (_>
H=# |-| (-) )-( }{ {-} /-/ \-\
I=1 ! |
J**=_| j
K=|< |{
L=1 |_
M=/\/\ |\/| \/
N=/\/ |\| \
O=0 ()
P=|D |* |>
Q=0,
R=|2 |? |-
S=5
T=7 + ']'
U=(_) |_| \_\ /_/
V=\/
W=\/\/ |/\| /\

there are many ways to write each letter in leet.
here are the most common:

A= 4
B= 8
C= (
D= |)
E= 3
F= |=
G= 6
H= |-|
I= !
J= _/
K= |<
L= 1
M= /\/\
N= /\/
O= 0
P= |>
Q= &
R= |2
S= 5
T= 7
U= |_|
V= \/
W= \/\/
X= ><
Y= '/
Z= 2
