"In the bus."
Translation:En el autobús.
el for 'masculine' nouns; la for 'feminine' nouns. You get used to which ones are which and most times there is consistency in endings, such as most nouns ending in 'o' are 'masculine' and most nouns ending in 'a' are 'feminine'. However, there are some that don't follow this 'rule', such as those ending in 'ma' (e.g. problema) which are generally 'masculine'. They have come in from a different language (in this case, Greek) and may get assigned a different 'gender' from the norm.
You should be able to hold your finger on a letter so that alternative letters based on that letter come up for you to select. So, for instance, if you want ñ, hold the n until a little panel of alternatives shows, then glide your finger over to the one you want to highlight and use it.
