- arguably
- arguablyis first recorded only in 1890, and did not appear in the original OED; now it seems indispensable. It is used as an ordinary adverb and as a sentence adverb (qualifying a whole statement). Examples:
• Arguably, this is another kind of corruption, but it was in general a very long-range bribery, and it was invariably offered in the guise of friendship —R. M. Sunter, 1986
• Vodafone is arguably one of our most successful companies —Sunday Times, 2004.
Arguably is best used in unverifiable contexts that are open to genuine argument and disagreement. In general use it tends to become weakened into a routine ‘downtoning’ adverb involving little or no argument and hardly more forceful in effect than is ‘possibly’ or ‘perhaps’; as such it is much espoused by those who are unsure of their facts or who may not have the courage of their convictions:• Meet the man with the surname everyone knows, Giorgio Armani, who arguably adorns more bodies worldwide than any other living designer —Clothes Show, 1991.
