Spanish Vocabulary contains 2,899 cards comprising a basic set of Spanish words, mostly from my textbook, Practical Spanish Grammar, Second Edition, by Marcial Prado. Other words are from the Harper Collins Spanish Concise Dictionary, Second Edition. The total number of words in the vocabulary is about 1,400.
Most cards (nearly all) have English on one side and Spanish on the other.
The words are arranged into categories for focused study. Certain categories (Adverbs and Adjectives, Nouns, Verbs, and Other Words and Expressions) are each further divided into three units, with the more basic words in unit 1 and the more advanced words in unit 3.
"Spanish" is first in each category name because I assume that you have other categories already in use and will want it to be obvious which categories are related to the study of Spanish.
For example, Spanish:Nouns:1
