Este or Este?
What is the difference between este (meaning the direction East) and este (meaning "between")?
(I'm not aware that este can mean in between, do you mean entre?)
Well, you wouldn't ever say "el este" if you were talking about "this." One is a noun, the other is an adjective.
But words spelled the same and that sound the same do not require the same definition.
What is the difference between fish and fish? One is an animal and the other is a verb.
este = east : el sol sale por el este.
éste = this one (and not another): Los dos platos son iguales pero yo quiero éste.
este = demonstrative pronoun: este plato tiene comida para perro.
esté = 3rd person singular, present subjuntive of ´estar´. Ojalá Ernesto esté bien en su casa
lo siento Kenwilliams pero I believe the tilde is over the first e (not the second) as in éste and yes it mean "this" when used for masculine words as in éste coche (this car). Feminine words would use ésta as in ésta mesa (this table) and again the tilde is over the first e. If you put the tilde over the second e, you would have to do the same with feminine words, making the word está which would end of being "it is a table".
To sum up what I am trying to say: éste = "this" for masculine words. ésta = "this" for feminine words. este = east. está = he/she/it/ is or you are (formal).
I'm still very new to the spanish language and have a tremendous amount to learn. But anytime I can put my learnings to the test and help someone in the process, I'm all for it. If anyone needs to correct me, please do so.
