Means “or”, because “or” includes “and”.
{{a|plainenglish|[[File:Andor.png|thumb|center|500px|for extra cosmological points, try the preferred EU formulation.]]}}{{f|And/or}} is the [[legal eagle]]’s equivalent of a damp kipper handshake. Avoid it. There is no more obvious sign that a text is in need of a [[plain English]] reaming.


And is "a Boolean operator which gives the value one ''if and only if all the operands are one'', and otherwise has a value of zero."
“{{f|And/or}}” ''means'' “{{f|or}}”, because “{{f|or}}” ''includes'' “{{f|and}}”.


Or is "a logical operation which gives the value one ''if at least one operand'' has the value one, and otherwise gives a value of zero."
That’s it.


Never speak of this again.
===In [[tedious]] detail===
“{{f|And/or}}” has a face only a mother could love. It is borne of the [[fear]] that, when considering alternatives ''any'' of which leads to a given outcome, things might somehow be different if they ''all'' occur.  


{{c2|egg|ISIA}}
There is no grounds for this fear. Logically, this is how one defines {{f|and}} and {{f|or}}:
 
:{{and}}
:{{or}}
 
===The and/or paradox===
Besides, [[and/or]] is not just ugly; it’s circular. It presents as a {{t|paradox}}, because of that {{tag|slash}}. Now the slash is not a part of idiomatic punctuation in the English language. It’s a decoration with no fixed grammatical meaning. To use a [[slash]] in legal writing is to confess that the ordinary, punctuated words of the English language have defeated you.
 
In “[[and/or]]”, that slash means — can ''only'' mean — “''{{f|or}}''”. So by saying “{{f|and/or}}” you are really saying “and, ''or'' or”. But to be hermetically sealed and consistent, shouldn’t you make one further clarifying step, and say “{{f|and}}, {{f|and/or}} {{f|or}}”?
 
AND DO YOU NOW SEE THE INFINITE REGRESSION YOU HAVE SET IN MOTION?
 
Go back to your draft and strike all examples, and we shall never speak of this again.
===Classic and/or fails===
Spotted in, where else?, an [[NDA]]:
{{quote|Disclosing Party may demand the return, and/or destruction and/or erasure of Confidential Information at any time.}}
You can’t have it both ways: You can’t return it ''and'' destroy it.
