PPRuNe has an auto-correct function that has several uses, one of which is to correct common spelling mistakes. You misspelt accommodation (1 m rather than 2), thus triggering the auto-correct.
Unfortunately, that function has a habit of adding the next word in the list to the resulting text, causing the outcome you have noted. It is probably down to incorrect formatting of the text strings in the auto-correct list, which will need an admin to check.
Note that I corrected your spelling and the spurious word no longer appears in your post.
