Questions & Answers about Voy a la escuela a pie.
The lesson says to use en for transportation. Why is it a pie instead of en pie?
In English we say 'on foot'. Does the preposition a also mean 'on'?
Not usually. Prepositions rarely match up perfectly between English and Spanish. While a typically means 'to' or 'at', in this specific case, a pie is just a fixed expression you have to memorize for 'on foot'.
Why does this sentence use a la instead of the combined word al?
The combined word (contraction) al is only used when the preposition a meets the masculine article el (a + el becomes al). Because escuela is a feminine word, it takes the feminine article la. The words a and la never combine into a single word.
Where is the word for 'I' in this sentence?
