Hola Randy

This lesson is about nationality adjectives that end in -e for both masculine and feminine. So the adjective has the same form when referring to a man and a woman:

el hombre estadounidense

la mujer estadounidense

You don't need to change the ending depending on being masculine or feminine. 

We give lots of adjectives for nationalities in the hint and you have to work out which one to use, i.e. if you see that the adjective ends in -e (as showing in the hint) and then the sentence is using a feminine noun, e.g "la gastronomía..., la cultura..., la lengua..., etc", you need to work out that, as it is an adjective that ends in -e you keep the same form for that feminine word."

Is there anything different that you struggle with?

Hola Randy and Aileen

The lesson will be revised to see if we can use other -e ending nationalities that are more common. Bear in mind though that we're not asking to memorize any odd nationality; in all test questions here you are offered the word in the hint; this is so you understand that if you have a nationality ending in -e (masculine) then you don't need to change it for the feminine form, as we do with regular adjectives ending in -o for masculine and -a for feminine.

In addition to that, there will be lots of students who would find that learning about nationalities such as "estadounidense" or "canadiense" to name some, is really useful. 

As said, we'll go back to the lesson to see if we can modify it in terms of using other easier -e ending nationalities. 

Saludos cordiales
