A cryptogram is a block of text which has been rendered unreadable through
the use of what is called a "substitution cypher".

This means that each letter used in the original text has been
substituted with another (G becomes A, F becomes P, etc.). Letter/word
positions, spaces and punctuation remain unchanged.
Cryptograms are solved primarily by two methods. First, pattern recognition.
The easiest to recognize are single-letter words, which generally can only be
A or I (or, rarely, O). Then there are a limited number of two-letter words
such as IN, IS, IT, TO, AN, AT, AS, WE, HE, US, etc. One trick in particular
is to look for the common TH- words, i.e. THE, THAT, THEN, THEY,
THERE, THEIR.
Secondly, the successful cryptogrammer will use letter frequency to help suss
out a difficult puzzle. The twelve most frequently-used letters in the English
language are ETAOIN SHRDL, in that order. The least common letters are
JXQZ. If you notice a certain letter being used again in again in any given
cryptogram, at a frequency much higher than any other letter, its a good bet
that its unencrypted form will be one of the ETAOIN group.
Finally, when all else fails, simple trial and error can generally fill in the gaps.
