Abridge and abbreviate both carry the idea of shortening so that what remains adequately represents the whole.

To abridge suggests the cutting away of nonessentials while retaining the core. To abbreviate, generally used in reference to words or phrases, implies shortening by the compression or omission of parts, the remainder standing for the whole: to abridge a novel for its inclusion in a magazine; the abbreviated name of an advertising agency.

There are some disagreements among lexicographers regarding which prefix should be used; so, some dictionaries don't bother to indicate a prefix.

One source, The Barnhart Dictionary of Etymology, presents the following: abridge, about 1303, abregen, "curtail, lessen", borrowed from Old French abregier or abreger, from Late Latin abbreviare, "to make brief".

—Compiled from The Barnhart Dictionary of Etymology
by Robert K. Barnhart, Editor; The H.W. Wilson Company; 1988; page 4.

Then The American Heritage Illustrated Encyclopedic Dictionary indicates that abridge comes from Middle English abregen, from Old French abregier, from Late Latin abbreviare, to ABBREVIATE.

It then says that the etymology of abbreviate is from Middle English abbreviaten, from Late Latin abbreviare, "to shorten": ab-, "off", or ad-, "toward" + brevis, "short".

So, which of the sources is correct? It appears that the American Heritage Illustrated Encyclopedic Dictionary took the easy way out by writing that abridge comes from ab-, "off", or ad-, "toward" + brevis, "short"; and this version is essentially shown above in #5, which is the Etymology entry.
