Baby steps toward understanding RNNs

Sentences can be thought of as combinations of words, such that words are spoken over time in a sequential manner. It is essential to capture this temporal relationship in natural language data. The presence of a word in a lot of scenarios might be influenced by words not necessarily in the immediate neighborhood. Think of the following sentences:
