Today we're going to talk about facial expressions! Facial expressions are called olisa ajinosa, types of faces.
There aren't words for specific expressions like a smile or a frown in Reisu. Instead we can say 'aji ida', or 'happy face'. We can also say 'Aji upa' or 'sad face'.
Leika aji ida! Make a happy face!
Make face happy!
Aji upa bei? Why the long face?
Face sad why?
Kuxadu aji ono idogi lo e. Don't get angry with him.
Don't-turn face 2PSingPoss angry to 3PSing.
Most obvious in the third example, it's more common in Reisu to talk about having a certain face than feeling the emotion itself. For example it would be better to say 'leika aji ida', 'make a happy face', than to say 'geki ida' (think happy, feel happy, or be happy).
You can also have aji imo, scared face; aji yifa, scary face; or aji haha, laughing face.
