Saying sentences / phrases aloud helps retention
Of late I have been saying each Spanish sentence or phrase aloud as I do it - it helps me remember the words as well as the sentence structure better. This works for me - i thought to share it!
I pronounce both the English and French/German/Spanish sentence. I usually pronounce the sentence I'm learning twice, before and after answering. If I'm not asked to translate but to write down a sentence I hear or to speak in the microphone then I try not to look at the translation, but to understand the sentence on its own. It might take a while to warm up, but it's nice to experience that things become easier to pronounce and to understand once have done a few lessons.
