In the past, the test makers published detailed lists of the vocabulary (as well as kanji and grammar) that would be found on the test. They no longer do this, but the older information should still cover the majority of what's on the new tests.
This list is based on the old information plus some new vocabulary confirmed to be included in the test.
Each vocabulary word is followed by a simple example sentence to give you context. There is also a sound file for each example sentence.
