Why Not the Subjunctive?
In Word of the day for 12/17/15, the first sentence given for agradar: "No te puedes imaginar cómo me agrada salir a bailar contigo, mi amor.", would seem to be a textbook example for using the subjunctive agrade here. Why was agrada chosen? Thanks in advance.

There have been many good answers given here regarding why the subjunctive is not needed. It's easier to see however, if you switch the word order around thus:
"¡Cómo me agrada salir a bailar contigo, mi amor, no te puedes imaginar!
How (much) it pleases me to go out dancing with you, darling, you can't imagine!
Not one bit of doubt here.

Would you please translate that to English?
I mean the sentence "No te puedes imaginar cómo me agrada salir a bailar contigo, mi amor."
"No te puedes imaginar cómo ....." is just an expression that is nothing more than an injection of emotion, so it doesn´t affect the following clause. There is nothing in doubt here.
A clear expression of doubt: No creo que puedas imaginar cómo me agrada.........
So called "cues" and "triggers" confuse those who study the language using these things, rather than relying on simple knowledge of when subjunctive should be used. There are many times when we have the choice between subjunctive and indicative as well, so it´s best to ask yourself if subjunctive is necessary or if you want to use it for the nuance you wish to create. After a while you will recognize certain word orders where you will see subjunctive used, but this is not an automatic usage but simply how we structure sentences when we want to use subjunctive.
Me agrada salir a bailar contigo / Salir a bailar contigo me agrada.
Either way you form this phrase it is a simple statement of fact made in present tense. There is no reason to use subjunctive.
I think that "No te puedes imaginar" is not a cue for the subjunctive because it is actually expressing a certainty rather than a doubt:
No te puedes imaginar = You can't imagine = There is no way you can imagine = Fact and indicative.
"No te imaginas" on the other hand may trigger the subjunctive because it could express doubt:
No te imaginas = You don't imagine = You don't really think (same as English) = Doubt and subjunctive.
Is that right Spanish speakers?
On page 264 of the 5th edition of "A New Reference Grammar of Modern Spanish" by Butt and Benjamin they say "The rules given in this section do not refer to question-words like cuándo, dónde cómo, which are not subordinating conjunctions and therefore take the indicative in both direct and indirect questions".
The rules for using the subjunctive seem to have more to do with syntax than semantics (meaning) so some of the answers to my question, which are given above, may be on the wrong track. The trouble I have is to remember all those syntax rules. The desire to give semantic explanations, based on communicating certainty or emotion, for why the subjunctive is used, is strong because they seem simpler than the syntax rules, but I am afraid they are far from foolproof.
