If you need a grammar reference, this may well serve until you find a better one. It might be of greater utility if the tone wasn't vaguely condescending and pedantic, and it eschews the panoply of actual examples in favor of definitions. To wit: the 2nd person singular present perfect conjugation of "to love" results in "If you have been loved..." gives me one (singular) example but not the rationale of when to use this. The density of the text preceding the example conjugations will require your own self-study to master (if you must) the ability to spin off a subjunctive 3rd person plural present tense conjugation.The best recommendation I can offer for this is as a companion for language learners who need a quick reference for English analogs of other-language conjugations, such as when you try to conjugate "falar" and need to know which one to use.--#

If I could give this half of a star I would. I am a big fan of Nirvana, but this was a total disappointment to me. The tracks sounded awful. I felt like I was ripped off in every sense of the way. I took it to a buy-trade-sell place and not even they would offer me anything for it, which shows you the poor quality of this album. A word of advice; DO NOT BUY THIS!!!!!

Ex Output:
Negative
