The prefix 'er-' is inseparable, so it always remains attached to the verb. It often means that something is successfully opened or made accessible, almost as the opposite of 'schließen' (to close) or 'verschließen' (to lock up, to close off).

When something becomes understandable, you use the reflexive form 'sich erschließen' (to become clear). The person who understands something is in the dative. The pattern is: something (subject) + erschließt sich + mir/dir/ihm (dative).
Der Witz war kompliziert; er erschloss sich mir erst später.
The joke was complicated; it only became clear to me later.
When you logically infer something from clues, you often use the preposition 'aus' (from). The pattern is: etwas aus etwas (Dativ) erschließen (to infer something from something).

In business, 'erschließen' (to open up) means to make new opportunities usable. Common combinations are 'einen neuen Markt erschließen' (to open up a new market), 'neue Zielgruppen erschließen' (to reach new target groups), or 'neue Geldquellen erschließen' (to tap into new sources of funding).
