Ejusdem generis

Of the same kind or nature. Where a class of things is followed by general wording that is not itself expansive, the general wording is seen as things of the same type as the listed items. For example, if damage from rodents, insects, or birds is listed as excluded, then damage from bears is not excluded as they are not a rodent, insect or bird.
***
Of the same kind.

Ejusdem generis rule

A rule of construction. If a specific phrase is followed by a general expression then the latter will be interpreted as meaning of the same kind as the specific words. If a policy refers to jewellery, plate, silver, gold or any articles’, the last three words mean ‘any articles of the same valuable kind as jewellery, plate, silver and gold’ and do not mean ‘any articles of any kind.
