can; to be able to; is possible to~
Expresses possibility or ability, equivalent to 'can' or 'to be able to', often in written or formal contexts.
得る is a formal or literary way to express possibility. It is often used in written language, news, or formal speeches. It conjugates irregularly: the dictionary form is 得る (eru) or 得る (uru) depending on the context. In modern usage, 得る (eru) is more common, but 得る (uru) appears in fixed expressions like あり得る (ariuru) and 考え得る (kangaeru). When attached to a verb stem, it indicates that something is possible or can happen. It is not used in casual conversation; instead, you would use ことができる or the potential form of the verb. For example, 食べ得る is possible but very stiff; you would normally say 食べられる.
