Capable of being cried about; worthy of tears or able to be wept over.
From 'cry' (Old English 'crygan') plus the suffix '-able' (from Latin '-abilis'), meaning capable of or worthy of an action.
English '-able' is so productive that you can attach it to almost any verb—'cryable' might not be in dictionaries, but any speaker would instantly understand it means 'something that makes you cry.'
