ㅅ irregular verbs

Some verbs and adjectives whose stem ends with a ㅅ 받침 are irregular.

When these irregular stems are followed by a vowel, the ㅅ is dropped.

Note that some verbs/adjectives with a ㅅ 받침 are regular: the ㅅ does not change. There is no specific rule to know whether it is an irregular verb or not; instead you must memorize which are irregular verbs and which ones aren't.
