I'm confused how to pronounce 'r' at the end of a word like in hablar, mujer, color, etc. I've listened to many of these words from many different speakers, and it sounds much closer to an English 'r' than a Spanish 'r'. When I record myself saying these words with an English 'r' rather than a Spanish 'r', I sound much more like native Spanish speakers. In particular, 'er' seems to be a sound all on its own in Spanish, like 'air' in English.
I find it difficult to pronounce the Spanish 'r' at the end of a word anyway, to have to cut it off, instead of having a vowel to roll it into. So I'm wondering, for sake of ease in learning, if I should pronounce these kind of words with the English 'r' instead.
