What does "innuendo" mean?

Innuendo: (Law) An averment employed in pleading, to point the application of matter otherwise unintelligible; an interpretative parenthesis thrown into quoted matter to explain an obscure word or words; -- as, the plaintiff avers that the defendant said that he (innuendo the plaintiff) was a thief. Wharton. Note: The term is so applied from having been the introductory word of this averment or parenthetic explanation when pleadings were in Latin. The word "meaning" is used as its equivalent in modern forms. An innuendo is an equivocal allusion so framed as to point distinctly at something which is injurious to the character or reputation of the person referred to. An insinuation turns on no such double use of language, but consists in artfully winding into the mind imputations of an injurious nature without making any direct charge.
