your question is not silly at all - and I admit that we haven't
always been consistent in the usage of these 2 terms. In general,
since "tableau" is french, "tableaux" is plural, and they are both
pronounced in exactly the same way, i.e., the "x" is silent. Now we
could think of a tableaux algorithm/expansion rules/etc. as an
algorithm/rules/etc. that uses/expands one or several tableau"s". Or
we could think of tableau algorithm/expansion rules/etc. as an
algorithm/rules/etc. that is based on the notion of a tableau...
Recently, I tried to be a bit more consistent in the usage of this
"x", but I think there are no general rules to it (apart from the
This problem is also considered elsewhere: for example, on the
discussion page of http://en.wikipedia.org/wiki/
Method_of_analytic_tableaux you find:
"The method is usually called (Semantic or Analytic) Tableaux (from
French?) as the Title also indicates. In the body of the page though
it is called Tableau. Should that be updated? DRap 09:09, 9 January
Yes, the word originally entered English via French. "Tableaux" is
plural (in both English and French, "Tableaus" is an alternative
English plural, but rarely used, and, to my knowledge, never in this
context), "Tableau" is singular. To add to the confusion, to my
German ear, they both sound exactly the same ;-). --Stephan Schulz

Yes, perhaps we could clarify? You will often see in the article 'a
tableau' and this should be made distinct from 'the tableaux' (is the
'x' silent?). I have seen it reffered to both as semantic tableaux
and tableau, but don't which would be more appropriate here
