having a lot of knowledge
Knowing a lot about a subject or many subjects.
Usage pattern:
[someone] is knowledgeable about [something]
Common mistake:
Learners sometimes say *"I am very knowledge"* instead of *"I am very knowledgeable"*; remember that *knowledge* is a noun and *knowledgeable* is the adjective. Another common mistake is choosing the wrong preposition; the most natural phrase is *knowledgeable about [something]*, not *knowledgeable of* in most cases. Also, *knowing* is not usually used in the same way; you say *"She is knowledgeable about history"*, not *"She is knowing about history"*. Spelling problems are common too: the correct spelling is **knowledgeable**, not *knowledgable*.
