I started reading this book because I was hoping to solidify my understanding of the subjunctive. Although I did pick up a few useful tidbits from this book, I was really disappointed with most of it. There were examples given that didn’t match the rules/patterns/exceptions explained in the book. For example, it gave the example “todo depende de cómo lo veamos,” but it never explained if or when “cómo” could be used instead of “que” to “trigger” the subjunctive, so I didn’t know if this could be done anytime or only in certain situations or what.
Also, it talked about the subjunctive being used only when there are different subjects, but I wasn’t clear on whether that only applied to situations where particular verbs are used before “que.” Also, the examples they gave for when the subject is the same didn’t have “que” in them, so I wasn’t sure if that meant that if you did include “que” then you would still use the subjunctive, or if you would just never use “que” in that situation and that’s why you wouldn’t use the subjunctive in that situation (it never explained this). For example, they gave an example like “Ver ella me hace pensar en mi hermano.” So if it used “que,” would it be “Ver ella me hace que piensa en mi hermano” or would it be “Ver ella me hace que pienso en mi hermano”? Or would you never use "que" in that situation (in which case they should explain that because it would make it a lot easier to understand why subjunctive isn’t used in that situation)?
The book advises not to bother remembering all the specific “trigger” words, which may be ok if you are just starting to learn Spanish, but it feels very impractical for the long term. We need to know these if we are going to communicate with any regularity with native speakers. I wish the book had included an index in the back with a list of all the “trigger” words and structures given throughout the book. It would be handy to keep a list at your desk to refer to and help solidify these in your head.
Some of the explanations feel very roundabout or backwards. For example, at one point there is a list of words that is labeled as “non-triggers.” However, they are actually words that use the subjunctive only if used with no/negation. I wish that is how they would be labeled in the book—otherwise, it appears as if these words never “trigger” the subjunctive.
There is a lot of advice in the book along the lines of “Don’t try to understand this, because you won’t. You’ll just have to get used to it.” This type of advice is frustrating to read, and I wish the author would focus more time on writing clearer explanations and covering all the information. At one point, they said this book doesn’t explain everything about the subjunctive, because it would be impossible to explain everything about the subjunctive in one book. This is about halfway through the book, and was very frustrating to read, because obviously if you are looking for a book about the subjunctive, you are hoping to learn everything about it so you can use it properly and understand it properly. I would have chosen a different book if I had known how limited this book would be.
Also, there are some casual statements throughout the book as though the author is trying to carry on a conversation with the reader and encourage them, but it can get a bit frustrating and condescending at times. For example, it will say “Do you get it?” And if your answer is “no,” there’s no help and you just get more frustrated by having someone remind you that you don’t get it. There are also occasional statements like “…you’ll find yourself making subjunctive sentences unconsciously and with ease,” which felt quite unhelpful for a book aimed at people who are obviously having difficulty understanding the subjunctive. I don’t think it’s reasonable (especially with the confusing explanations and examples, and the author’s own admission that this book doesn’t have all the information about the subjunctive) to suggest that you will fully understand the subjunctive by the end of the book, much less use it “unconsciously” and “with ease.” That just feels like the author is setting unreasonably high expectations for the reader, which gets to be frustrating after a while. I was sitting there struggling with basic questions about which words require the subjunctive and which ones don’t, and reading that just felt like the expectation was that I should soon be using the subjunctive so well that I’d be using it “unconsciously,” which I knew was impossible, so it just made me feel like giving up.
I had to take multiple-day breaks in between reading short sections of this book, because I found it so frustrating and unhelpful. I kept at it because I kept telling myself that it must be helpful, because I had seen other people rate it highly, so I figured maybe most of the helpful information was near the end, or that something would “click” towards the end and that the information in the first part of the book would finally make sense (it didn't).
I’m glad others found this book helpful, but I’m not clear on how they managed to learn all they needed to learn about the subjunctive from this book. I ended up reading a second book on the subjunctive later (Practice Makes Perfect: The Spanish Subjunctive Up Close, Second Edition), and that one was much more precise and detailed, and helped me a lot more.
