The English word 'to' can have multiple uses and is especially fluid in use. In Arabic different words are used to represent it within a sentence based on how the sentence is worded and its meaning. 1. "I went to the show" - to is 'ila' here 2. "To sail in a boat is..." - such a sentence is rarely started the same way as the English sentence, but in this case it can be 'li...' or 3. "To bake a cake you..." - 'hatta' (implies a question was asked).
