Questions & Answers about Nos comimos el sándwich entero y tuvimos una indigestión terrible.
Why is it nos comimos instead of just comimos?
The nos here is an affective dative (also called dativo ético). It doesn't mean we ate ourselves. Instead, it emphasizes the completion of the action or the emotional involvement of the speaker. In English, we often express this idea by adding "up" (we ate up the sandwich). It adds a subtle feeling of indulgence or totality.
Would the sentence still be correct if I left out the nos?
Why does the word sándwich have an accent mark if it's an English word?
Even though it's a loanword, it has been adapted to follow Spanish spelling rules. Words stressed on the second-to-last syllable that end in a consonant other than n or s need a written accent mark. Since sándwich ends in ch and the stress falls on the first syllable, it gets a tilde on the a.
Why do we need the article una in una indigestión terrible? English just says "we had terrible indigestion."
