Word of the week in English:
peculation=embezzlement "The peculations of small Italian businessmen lack charm" (A. Lurie)
Word of the week in French:
occire (pronounced ox-ear)=to slay (says it's either obsolete or humorous - I can identify with that): "Mais pourquoi qu' t' as occis le mataf?' (Genet - yes, that one) - "Why did you slay the sailor-guy?'
