Deme vs Dale vs Dele
I am using Rosetta Stone. Here are three statement-replies taken from the program:
Statement 1:"Dale un juguete." Reply 1:"Ella le da un juguete a él."
Statement 2:"Dele un boligrafo, por favor." Reply 2:"Ella le da un boligrafo a el."
Statement 3:"Deme un paraguas, por favor." Reply 3:"él le da un paraguas a ella."
What is the difference among "dale," "dele," and "deme"? And under what conditions would you use each one? Your help is much appreciated.

Welcome to the forum, Beachlover!
If you go to the top of the page and click on "conjugate" and put in the verb "dar" you will see the full conjugation of this verb. This will provide an important framework for your understanding.
I'm not going to explain everything to you, but I will explain things that you can remember, I hope.
Next, put yourself in the mindset of a two year old. The imperative or command, of "dar" is "de" and "deme" means "give me." This is the polite (Ud.) form. Now you can go travel the Spanish-speaking world demanding people give you things in Spanish, Pretty powerful, huh? You demand anything, once you learn the appropriate nouns, that is. You can put this into practice immediately. Deme un paraguas, por favor. Give me the umbrella, please.
"Deme" is the imperative (command) in the polite *Ud." form -- Give me. "Dame" is if you know the person really well, the "tu" form.
The "le" indicates a third person. I'll let you figure out the rest of it using the conjugation chart.
