1~れる
Potential form.
This verb form expresses the ability or possibility to do the action described by the verb, as in 食べられる (can eat), 飲める (can drink), and 泳げる (can swim). As you can see, the potential form is similar to the word "can," but it is built into the Japanese verb rather than a separate word like in English.
