extraneous
(formal) That which constitutes no necessary or natural part of anything; proceeding from without; irrelevant. The word is considerably general in its implications, but may suggest a difference in kind (‘hard-core facts’ vs. ‘extraneous interpretation’).The inessential element referred to may, if not excluded, be either harmless or detrimental (‘extraneous poisons’, ‘ext. odours’).Omitting the extraneous matter and concentrating on essentials, sir, Mr Gorringe wishes to borrow £1,000 from you.
